running two copies of this will exit when you activate the macro-attached cells
This macro spreadsheet works really slick SOME of the time. But it only allows ONE instance of the document to be open at a time. If two copies are opened, then the macro crashes (soffice.bin process dies) almost immediately.
The macro does an account lookup when you type something in the D column.
Actually, this document crashes fairly easily anyway, even if only one copy is open. The crash seems to mostly happens if you go BACK to a D column cell that you previously touched. Moving forward by just doing data entry generally works rather well. I haven't been able to "predict" a crash by doing a particular sequence, but selecting multiple D column cells and then clicking again on a single D column cell often triggers the crash.
I'm sure there are several bugs involved here. The focus of this bug report should be running multiple instances of VBA simultaneously.
I THINK it crashes more easily in Linux than in Windows, but it does crash in both.
Our global organization uses Excel for finances, but we are moving to LibreOffice in some of our branches. We updated the VBA macros so that they work in both Excel and Calc. In normal practice, we would like to have multiple copies of this spreadsheet template running simultaneously as we do data entry.
Note: in order to make any debugging changes to the macro code, MS Office Excel MUST be used. LibreOffice calc is designed NOT to be able to change VBA code. Ignore Modules1-5. The VBA in question is in Module:AccountLookups and Sheet1 and the form frmListPicker.
I can reproduce crash with Version: 126.96.36.199.alpha2+

This gdb was created using a single document, entering four accounts, and then moving up through them one by one. Crashed when I got to the first account. Using 4.4.0 development build with some additional SAL_WARN statements added.

I took a slightly different approach this time. Again using a single document, this time I manually filled in a few D column cells without using the macro. Then I turned the macro on and moved to a pre-populated cell. It crashed immediately.

reduced macro code to the bare minimum
I worked on isolating the part of the code that seems to be causing the crash. It seems to crash when a call is made to txtValue_Change() - which a textbox element calls when the value changes.
Private Sub txtValue_Change()
'If this function is completely blank, it seems to not crash
MsgBox (txtValue) 'this is enough to cause the crash
txtValue_Change() is not called when clicking on an empty cell, which is why I can do normal data entry OK.

trace from Macro crashing copy2.xls. Even more SAL_WARN statements added.
A note in the code reminded me that txtValue_changed() was NOT always called in Linux when assigning a value to it, although I noticed that it IS changing now. So I ran a bibisect. Crash didn't happen before this function was implemented.

adjust magic binary index that identifies the theme name res id
because libreoffice inserted a bunch of extra resources since fork point.
We should get rid of these ids entirely and e.g. at least instead use the
filename number as the the id instead which would be a little less painful.

support api initiated change_event for combox & textbox
Created attachment 110161 [details]
bibisect: confirming that "support api initiated change_event for combox & textbox" definitely is the change that triggered the crashing. The changed added a call to "fireChangeEvent()".
Doing a "step into the macro code", the crash happens when txtValue_change()'s "Exit Sub" is evaluated.
gdb crashes vary in their reports of the specific crash point, but a recurring place is at /data/justin/git/libreoffice/basic/source/sbx/sbxvar.cxx:207
207 delete pCst; // who knows already, onto which thoughts someone comes?
Changing status to Linux only. Windows doesn't have the problem clearly exhibited in Linux.

sorry, I've missed the compression part of my previous traces. They are just tar's....
since the bibisect (comment #7), my gdb traces are based on the 4.1 code from Noel's commit.
I was able to get Windows to crash once with this test case - but it doesn't happen nearly as often.
From the backtrace I think this is just a duplicate of now fixed bug 86843. Can you try again with that fix in place and see if i can be reproduced?
I am no longer seeing crashes since the two dependency bugs were fixed. Closing this bug.
