Bug#872912: gnome-orca: Segmentation fault when switching between windows.

Robert Schindler robert at shajil.de

Package: gnome-orca
Version: 3.24.0-1
Severity: important

Dear Maintainer,

Orca crashes when switching between different apps (e.g. terminal
windows) while the system is busy.

This behaviour is reproducible on my system:
- Open two gnome-terminal windows.
- In the first, run "git gc --aggressive --prune" inside the cpython
  repository to make the system busy.
- Wait 20 seconds until git starts compressing stuff.
- In the second window, run "orca --debug".
- Wait 3 seconds
- Press Alt+^ (once or twice) to switch back and forth between the two
  windows.

Orca now crashes with a segmentation fault. I have a 44k orca debug
file, if that helps.

I got the same results with orca+atspi+pyatspi from stable and testing
(orca 3.22 vs 3.24 / atspi 2.22 vs 2.24).

Such crashes are very likely to happen if all CPU cores are busy, but
they also happen when the system is almost idle, but less often.

Best regards
Robert
