Bug#512565: totem-xine: Segmentation fault when disabling visual effects
reassign 512565 libxine1 1.1.14-4 thanks Le jeudi 22 janvier 2009 à 19:26 +, Laurentiu Pancescu a écrit : I can also reproduce the hang by clicking the visual effects checkbox while audio is paused (it happens at the first click, going from disabled to enabled, unlike the segmentation fault). After it hung, I stopped it with Ctrl-C in gdb and generated another stack trace for the hang (attached). I assumed it's the same bug as the crash, but the stack trace looks somewhat different. Should I file another bug for the hang? This is indeed a different bug (race condition vs. deadlock), but the root cause is the same: xine-lib doesn’t seem to support correctly enabling or disabling visual effects at runtime. In the crash issue, it is trying to access a resource that has been freed, presumably from another thread. In the deadlock issue, it is waiting for a mutex that will never be released since it has been freed in the meantime. (The very idea of freeing a mutex that may be used at any time is, well, “interesting”.) -- .''`. : :' : We are debian.org.

Thanks for the quick reply. I attached a stack trace of the segmentation fault. I noticed that sometimes it takes multiple clicks to enable/disable visual effects to produce the crash, but it always seem to crash while disabling them, never on enabling. totem-segfault.txt.gz Description: GNU Zip compressed data

I can also reproduce the hang by clicking the visual effects checkbox while audio is paused (it happens at the first click, going from disabled to enabled, unlike the segmentation fault).

Package: totem-xine Version: 2.22.2-5 Severity: normal I always get a segmentation fault if I disable the visual effects while a MP3 is playing (you can use one of the free German files from Deutsche Welle to reproduce the bug [1]). totem-xine terminates after displaying Segmentation fault in the console, and it logs the following message to the system log: totem[6951]: segfault at 10 ip b7b660f5 sp b38702a0 error 4 in libxine.so.1.23.0[b7b3b000+46000] If I first pause the audio playing before disabling the visual effects, totem freezes completely and I have to kill it. Unlike the segmentation fault, no error or log message seems to be produced.
