Description Paul Osmialowski 2024-05-09 13:17:37 UTC
This was quite hard to catch as it occurs very rarely (yet I'm starting to suspect it happens usually after recompilation). After quitting motion (with Ctrl+c), it sometimes, very rarely segfault. The trace looks like this:

Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007f38f94e1477 in __malloc_arena_thread_freeres () from /lib64/
[Current thread is 1 (Thread 0x7f38dbfff6c0 (LWP 17165))]
(gdb) bt
#0  0x00007f38f94e1477 in __malloc_arena_thread_freeres () at /lib64/
#1  0x00007f38f94d107c in start_thread () at /lib64/
#2  0x00007f38f954cb18 in clone3 () at /lib64/

Reproducible: Always

Steps to Reproduce:
1. build and configure media-video/motion
2. run motion
3. quit motion with Ctrl+c
Actual Results:  
Sometimes it segfaults when quitting.

Expected Results:  
It should never segfault.
