#9845 closed Bug Report - Crash (Fixed)

Segfault when starting Live TV

Reported by: skd5aner <skd5aner@…> Owned by: danielk
Priority: minor Milestone: 0.25
Component: MythTV - Video Playback Version: 0.24-fixes
Severity: medium Keywords:

Description

I'm getting segfaults about 20% of the time when trying to launch Live TV. It's repeatable, but I've not yet been able to understand exactly how to reproduce it. Sometimes it crashes, sometimes it doesn't. I was able to get a backtrace and launch mythfrontend with gdb and luckily catch one of the segfaults. I do not know of an exact behavior pattern that will cause the segfault, other than launching live tv.

Attached is the backtrace, log with -v playback (if I remember correctly), and version info.

Reporting back some recent testing...

After disabling the the setting for displaying the guide at the startup of live TV, I'm no longer able to reproduce this segfault. When I re-enable the setting, I sporadically get segfaults again.

skd5aner, this does not look to be related to #10416. But I'm not able to reproduce.

Are you still able to reproduce this?

I tested a few months back (December) with the latest version of 0.24-fixes at the time, and was able to reproduce (sporadically) if I had the setting to enable the EPG to show when Live TV is started. If I disabled that feature, the segfaults disappeared.

I'll attempt to test again over the next day or so with the setting re-enabled and report back. Please let me know if there's anything specific you'd like me to attempt/report back with.

I was able to reproduce this very easily using v0.24.1-112-g40f3bae

Turn on the setting to show the EPG when starting Live TV, and it segfaulted immediately when I used the Live TV jump point.

skd5aner, I need you to test with the master branch. I've a segfault fix in the guide there that has not been backported to 0.24 fixes.

I believe this is fixed in master. Please ping if you are able to reproduce.
