Do you reproduce this if you disable OpenGL?(see https://wiki.documentfoundation.org/QA/FirstSteps) If no, could you attach <user profile>/cache/opengl_device.log ? (see the same link) Finally, could you check you got the last drivers of your graphic card?

With crashreports, let's put this one to NEW. I submitted a patch for review here: https://gerrit.libreoffice.org/#/c/49186/ It's more a workaround since it blacklists this graphic card for OpenGL use in LO. I don't know if it's the right thing to do, that's why I'll wait for LO dev experts respond.
Hi, So, we can't use OpenGL with LibreOffice with these pretty good video card ? I hope you will find what it crash with these type of video card. Thanks in advance. Best regards
Meanwhile for the test, and if you got some time, could you give a try to a daily master build http://dev-builds.libreoffice.org/daily/master/Win-x86@42/current/ ? Indeed, some threading/timer part may have been fixed which may help here.

In my case the error is reproducible with opengl enabled and disabled. Only runing libreoffice in safe mode seems to work. Tested with opengl enabled -> steps to crash -> crash restarted Libreoffice. disable opengl in the options close libreoffice restart the machine (paranoid much?) start libreoffice check if the opengl option is still disabled -> it is. check if crash occurs -> crash. If matters, my card is an AMD radeon R9 390, 8 Gb vram.
@Telesto, @V Stuart, any change it can be bisected?
@Michael M.--See the debug trace from Comment 16, the crash here really only occurs with OpenGL rendering enabled. Why drop it from the META?
Oh - I was rather convinced by comment#18 =) Its great to see the trace there ! should make things much easier ... nice work.

Bibisected to the commit referenced below using repo bibisect-win32-6.0 (and a dictionary added to instdir/share/extensions, so Check for Updates is active in Extension Manager).

Either mpProvider is equal to nullptr and it returns true without testing second condition (and so without trying dereferencing nullptr) or mpProvider != null and we enter the second condition without pb of nullptr dereferencing.
My crash report signature is different from what's indicated in the crash report field: http://crashreport.libreoffice.org/stats/crash_details/a4ce0839-1ec7-4ad7-a7d4-68e9a91ef1cf

Deleting an object doesn't set its pointers scattered in the code to nullptr.
(In reply to Aron Budea from comment #26) > ... > Deleting an object doesn't set its pointers scattered in the code to nullptr. I agree with you but why you're talking about deleting an object here? Indeed, https://opengrok.libreoffice.org/search?project=core&q=mpProvider&defs=&refs=&path=&hist=&type= shows no call to delete on mpProvider.

The deletion must've happened somewhere else, since this class is not the owner of mpProvider, the pointer is passed in via the constructor.
Aron's analysis is basically right =) we invoke a virtual function call on an already deleted instance of the mpProvider - clearly the way the lifecycle of that and the management of pointers to it got messed up somewhere.
I can't reproduce this, because I'm running Windows in a KVM without OpenGL, and the crash is OpenGL related. From the backtrace I guess we schedule an flush on the dialog, which is gone at this point. OTOH the patch is not responsible for the crash, but it changes the timing of processing events, so that race may have been there for much longer.
I assume this can be added to VCL-OpenGL again.

(In reply to Jan-Marek Glogowski from comment #30) > From the backtrace I guess we schedule an flush on the dialog, which is gone > at this point. The OpenGLFlushIdle object for the crashing operation is created long before the WinSalFrame is destroyed. I have put action breakpoints to both OpenGLFlushIdle constructor, and WinSalFrame destructor, that would output the frame's pointer address to console. Then I started the debug according to steps in bug 115975; closed the confirmation dialog using "Cancel"; and got the crash. I have examined the console output to see a number of OpenGLFlushIdle objects that got constructed prior to the destruction of that WinSalFrame which was used afterwards in the crashing flush. Next, to see if there might have been some async console output that could reorder the lines, I did the same again; but this time, before hitting the "Cancel" in confirmation, I switched to VS, and cleared the console. Then I returned and clicked "Cancel", and got the crash. This time, console only contained the dtor line, without any prior creation of OpenGLFlushIdle objects (that, obviously, were created even before clearing the debug console). I am not familiar with this corner of the code; so I don't know where to look now. But it looks like some idle processing hasn't happened in the lifetime of the dialog. If this helps, we could arrange a desktop sharing to debug this on my system.
(In reply to Mike Kaganski from comment #33) > I have examined > the console output to see a number of OpenGLFlushIdle objects that got > constructed prior to the destruction of that WinSalFrame which was used > afterwards in the crashing flush. ... and one of those constructed OpenGLFlushIdle objects indeed was the one for the WinSalFrame in question.
Anyway it looks strange that the event objects aren't ref-counted, and not interlocked for the duration of execution. The OpenGLFlushIdle object is created in OpenGLSalGraphicsImpl constructor (and is held in unique_ptr); a naked pointer to it is saved in ImplSchedulerData and put into scheduler task list, and its usage might happen after the OpenGLFlushIdle has already been destroyed. I'd expect it behave more reliably if Task was ref-counted, and its owner would flag it disposed (but not destruct), so that scheduler knew that the task should be discarded; and the operations were guarded by a mutex (just an idea).
Hi Mike; thanks for that - a valgrind trace would perhaps show where the data was allocated - but I guess just code reading around the lifecycle of the flush handler and more to the point the mpProvider - which must get out of sync somehow and not cleanup its graphics. Unfortunately the SalGraphics lifecycle from what I recall is -crazy- that thing is re-created and switched between Windows left & right which needs de-bonging too really but ... ;-) HTH.
*** Bug 116115 has been marked as a duplicate of this bug. ***
Presumably the OpenGLSalGraphicsImpl (and other SalGraphicsImpls too) - and its associated WinSalGraphics survives longer than the SalGeometryProvider which is either a SalFrame or a SalVirtualDevice. Then again the apparently deranged lifecycle of SalGraphics as they relate to SalFrames etc. is something of a nightmare: // SalGraphics or NULL, but two Graphics for all SalFrames // must be returned virtual SalGraphics* AcquireGraphics() = 0; virtual void ReleaseGraphics( SalGraphics* pGraphics ) = 0; So - working out what has failed to release the WinSalGraphics is probably non-trivial; particularly as the bisection is reasonably unhelpful.
Hmm - then again ... looking at the code: vcl/win/window/salframe.cxx It puzzles me: WinSalFrame::~WinSalFrame() { // Release Cache DC if ( mpGraphics2 && mpGraphics2->getHDC() ) ReleaseGraphics( mpGraphics2 ); Doesn't seem to do anything of the sort; unless mpGraphics2 == mpGraphics. Indeed the condition: void WinSalFrame::ReleaseGraphics( SalGraphics* pGraphics ) { if ( mpGraphics2 == pGraphics ) { Looks deeply counter-intuitive; surely that should be mpGraphics2 != pGraphics - ie. only free it if it is different ? I'm left puzzled by who frees mpGraphics2 - which (after all) has this timer associated with it. Of course, that is not related to GL, and perhaps is a leak but only when used threaded: WinSalGraphics* mpGraphics; // current frame graphics WinSalGraphics* mpGraphics2; // current frame graphics for other threads The rather grim extensions code being high on the awful threaded, graphical code list of horror. Thoughts much appreciated; I append a blind fix in case someone can reproduce this and can compile that. diff --git a/vcl/win/window/salframe.cxx b/vcl/win/window/salframe.cxx index 64b073f99139..fee8440cc700 100644 --- a/vcl/win/window/salframe.cxx +++ b/vcl/win/window/salframe.cxx @@ -926,6 +926,17 @@ WinSalFrame::~WinSalFrame() mpGraphics2->getHDC() ) ReleaseGraphics( mpGraphics2 ); + // Why did we never do this ? + if (mpGraphics2 != mpGraphics) + { + if ( mpGraphics2->getDefPal() ) + SelectPalette( mpGraphics2->getHDC(), mpGraphics2->getDefPal(), TRUE ); + mpGraphics2->DeInitGraphics(); + ReleaseDC( mhWnd, mpGraphics2->getHDC() ); + delete mpGraphics2; + mpGraphics2 = nullptr; + } + // destroy saved DC if ( mpGraphics ) { But quite possibly I'm confused =) it happens.

After applying the patch, I'm getting assertion failed at startup: "vcl/win/app/salint.cxx Line: 611 Expression: !pInst->mbNoYieldLock" Note that I pulled ~1.5 weeks ago, so the sources aren't the freshest.
Can you get a trace for that assertion failure ? looks odd =) thanks !

Don't confuse the mpGraphics with pGraphics. I did it quite some times when reading the code. But we seem to leak the mpGraphics2 object, which is assigned once, but never freed. I'm now definitely preferring an *m_* prefix for member variables.
