I had not expected a gdb output that big and unfortunately
therefore it might got not accepted in the bug tracker,
therefore forwarding again.

With the attached file I still could not reproduce the crash,
but found from the gdb output it uses this file:
    /usr/lib/freecad-python3/lib/libFreeCADGui.so

But on my test VM I could first just see a usage of python2 version:
    /usr/lib/freecad-python2/lib/libFreeCADGui.so

So I installed freecad-python3 and removed freecad-python2,
but still could not reproduce the crash.

Maybe, as a workaround, you can try to use freecad-python2 and
remove freecad-python3 and see if the problem still shows up.

Now, I guess, we have to wait for the maintainers opinion
about what looks like a stack exhaustion.

Kind regards,
Bernahrd
