Firefox closing triggers marco crash

planet4589 commented 3 years ago

Expected behaviour Firefox dies, but marco should be fine

Actual behaviour marco segvs and has to be restarted. Details: windows lose decorations/menus, mouse focus is nowhere and cannot be regained (but can move cursor still). Have to ctrl-alt-f1 to get terminal to restart marco

Steps to reproduce the behaviour Close firefox, or wait for firefox to crash (as it often does). The first triggers the behaviour about 30% of the time, the second 100% of the time.

MATE general version Mint 20.1 install Mate 1.24.0

Package version 1.24.0

Linux Distribution Mint 20.1

Please, check the logs to see whether there are any traces of the segfault in order to provide more information.

Sorry, I didn't mean to close the issue, dunno how that happened

Don't worry about it.

Everything indicates that there is a null point deference in meta_frame_calc_borders, after freeing memory, the pointer is not NULL. We will have to review the destructive methods.

Thanks, I appreciate you looking into it.
