You can reproduce it after deleting ~/config/settings/VideoLAN Client/cache/plugin-04041e.dat file.

Component: - GeneralSystem/runtime_loader

This issue is introduced in hrev39306.

comment:4 by bonefish, 10 years ago

A possible cause could be concurrent modification of the image list by another thread (e.g. by unloading of an add-on). Enclosing the function body in rld_lock() ... rld_unlock() might solve the issue in the runtime loader (though I wonder if there was a reason why it had been omitted in the first place). VLC will possibly still crash, though, as the situation hints that the application shutdown isn't properly organized.

(In #7368) Yep, looks like a dup of #6803.

comment:6 by diver, 10 years ago

FWIW, hrev39305 also has something to do with topological_sort.

After installing this crash goes away.

I can't reproduce this with VLC 0.8.6i (BeOS version downloaded from Haikuware). Is it still a problem?

comment:9 by diver, 6 years ago

Still reproducible with vlc-0.8.6d at least in hrev48230.

comment:10 by waddlesplash, 6 years ago

Why do we care about 0.8.6d? d < i.

Replying to waddlesplash:

Why do we care about 0.8.6d? d < i.

If you'd actually read the ticket, you'd notice it's triggering what's potentially a bug in the runtime loader.

Summary: VLC crashes on exit (topological_sort)VLC crashes on exit (topological_sort) .. and other apps with add-ons?

Got word from dsuden, he just started seeing this on hrev48297, SP crashes every time it's shut-down (so not too annoying). See below.

Oddly he gets not just one but two segv's in two threads (the second crash does not seem related to topological_sort though).

Let's make the title a bit more general indeed, "vlc crashes.." is a bit misleading. Searching tickets for keyword "topological_sort" yields results for Deskbar (with add-ons), VLC (presumably with add-ons), and now our build of SP (which has a dozen add-ons loaded).

(In #12070) VLC version from HaikuPorts is broken atm. AFAIK, it needs some fixes to be able to use newer ffmpeg. You can use repackaged version of VLC from with ffmpeg lib compiled in.

The crash is a dupe of #6803.
