Bug 377255 – stabilize =media-libs/libass-0.9.13 (was: media-libs/freetype-2.4.6 causes crashes when playing media with styled subs with <media-libs/libass-0.9.13)

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mike MacDonald 2011-08-01 10:20:52 UTC]

=freetype-2.4.6 causes crashes when playing media in multiple players (mplayer, mplayer2, vlc) with styled subs with <libass-0.9.13.

This issue is known to libass upstream.

As freetype-2.4.6 is in unstable, this issue potentially effects a lot of users.

Reproducible: Always

Steps to Reproduce:
1. open a media file in mplayer or vlc with styled subs
2. wait until some fancy sub shows up (e. g. karaoke)

Actual Results:  
player crashes with SIGSEGV.

Expected Results:  
Normal Playback.

This happens with any player that uses libass for styled subs. Bumping libass to >=0.9.13 fixes the issue. (Simply renaming the ebuild is sufficient.)

Is there a bug report or mailing list thread referring to this.  Maybe we can backport a patch.

Is above enough ?
Though a stable request (as it's in the tree now) would still be more simple.

Cool, thanks.  We'll let media-video decide which is best.

This now affects Gentoo x86 stable.

Created attachment 284279 [details, diff]
backported patch

I backported that commit to mplayer-svn a while ago, seems to work fine.

Freetype-2.4.6 doesn't check border->start in ft_stroke_border_close (in src/basr/ftstroke.c:347) and when it equal -1 crashes cause.

Is it possible to stabilize >=libass-0.9.13 or patch freetype-2.4.6?

freetype is stable and this bug affects stable. Arch teams, let's stabilize =libass-0.9.13. The only reported regression (bug #378951) is not worth to wait any longer (also actually it's not very clear that it is regression or bug in libass).
