[Octave-bug-tracker] [bug #45540] Segfault when moving the mouse over Qt figures

[Pantxo Diribarne]

Follow-up Comment #31, bug #45540 (project octave):

Can you attach a back-trace of the crash? As the one you attached in comment
#23 does not contain very useful info, I suspect you don't have debug symbols
enabled.

Here is the nasty way I use to produce back-traces with the gui: 
* build default Octave with debug symbols: 
$ ./configure CXXFLAGS="... -g -O0"; make
* run gdb on octave-gui binary directly: 
$ gdb ./src/.libs/octave-gui
* then in gdb run Octave and produce the backtrace after the crash:
$ run
... 
$ bt
