Bug ID: 86843
Summary: vba crashes after fireChangeEvent is called
Product: LibreOffice

Hardware: Other
OS: All

xls macro that demonstrates crashes when combobox, radiobutton, textbox values
are modified using VBA code
On Fri May 10 17:04:39 2013, VBA was updated so that the change() routine of
textboxes and comboboxes would be triggered if macro code sets the value.
LibreOffice frequently crashes (complete exit) when that happens.
This could easily be the same problem noted in bug 86667, but I wrote in that
bug that it should focus on the "two documents" part of the crash. I'll mark
that one as depending on this bug, which will focus on a crash with a single
document open.
This commit added the fireChangeEvent call:

To replicate the bug: Use the test document by clicking on a non-empty cell,
which will set the control's value to the value of the cell. The crash occurs
VERY easily in Linux - usually within the first three cells selected. On
Windows it can also crash, but with much less frequency.
If you use the VBA debugger to "step into" the code, you will see the crash
happening when you "Exit Sub" from a change() routine.
I found three controls in the libreoffice codebase that call fireChangeEvent().
All three are included in the test document, and all can cause the crash.
