The document I want to open

Export UNLOCK_FPS_MODE=1 and open the document. The window will twinkle and then crash.

I record a video to show how to reproduce this bug, the link is as follow: 

I also upload the document that I want to open.

Please tell us what version of LibreOffice shows the problem and what
platform you are using.

Note, most importantly, that I am *assuming* that my crash, with
terminal messages:

    /usr/include/c++/4.8/debug/safe_iterator.h:293:error: attempt to increment 
        a singular iterator.

    Objects involved in the operation:
    iterator "this" @ 0x0x7f5f8a065cd0 {
    type = N11__gnu_debug14_Safe_iteratorIN9__gnu_cxx17__normal_iteratorIPPvNSt9__cxx19986vectorIS3_SaIS3_EEEEENSt7__debug6vectorIS3_S7_EEEE (mutable iterator);
      state = singular;
      references sequence with type `NSt7__debug6vectorIPvSaIS1_EEE' @ 0x0x3146ce8
    Application Error

    Fatal exception: Signal 6

sheds light on the reporter's problem.  Unless xukai is running a
dbgutil build, I think that the original crash cannot be exactly the
same as mine.

From the command line, I opened:

    CalcExtDemo\ -\ V10.0/Calc_Demo_Version10.0.ods

from the attached .zip file.  When prompted to enable macros, I denied

Comment 2 xukai 2014-09-28 02:04:38 UTC
The crash is caused by thread conflict. Following patch introduce this issue:
I suspect the patch has not been verified before commit.
The issue can be resolved if I add thread synchronization logic in my work environment.
Comment 3 Michael Meeks 2014-09-29 08:38:50 UTC
Hmm, my fault for rubber stamping this I think; lets go over this together when you get in Kohei =)
Comment 4 Michael Meeks 2014-09-29 16:37:26 UTC
Thanks for the clean report; confirming etc. & taking a look.
Comment 5 Michael Meeks 2014-09-29 19:55:11 UTC
Ah; you have to export SCROLL_RATE=100 as well or somesuch.
Re-adding the lock there appears to make life better; I've committed that to master; thanks.
Really we shouldn't have the chart mutex locked while we're in SwapBuffers AFAICS - it'd be the ideal time to re-build the chart model in another thread then while the GL drivers are doing their stuff.

Then again - the new, faster Windows main-loop, my hope would be that we could get a nice high FPS here without resorting to the over-complicated and fragile threading.
Comment 6 xukai 2014-09-30 05:41:31 UTC
Some other things which are not easy to be notice must still exist. It works fine if we don't enable the data updating, but it will crash and not smooth if we enable the data updating.
