[Bug 1094499] Re: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters()
Using libdvdnav 4.2.0-1ubuntu0.1 and vlc 2.0.8-0ubuntu0.12.04.1, I still get this crash with DVD Shadow Recruit (at dvdnav_describe_title_chapters(), stack trace says it is under package vlc-nox 2.0.8-0ubuntu0.12.04.1). Also happened with Madagascar and several others, although the package may have been updated since then. BUT, the same crash occurs in VLC 2.0.5 running on Windows XP on a totally different machine. I can't verify the stack trace under Windows, but VLC behaves exactly the same way -- closes itself a few seconds after attempting to open the DVD. I don't think it's a region issue, both DVD players should be the same region as the DVDs I am playing. Each time, the DVD works fine under Media Player Classic (for Windows). It didn't occur to me until recently to try it on Windows. So out of all the problematic DVDs, I've only tried 3 on Windows as well. However, all of those had the same issue under Windows. Today I updated VLC on Windows to 2.1.3 and the Shadow Recruit DVD no longer crashed. I hope this may be useful to someone. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094499 Title: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdnav/+bug/1094499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1094499] Re: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters()
Colin, mind opening a new bug for that dvd issue? That looks like a crash due to a bad pgc-cell_playback_offset value, which is different from this bug. This one is already closed and considered fixed, so no further work is going to be done on it. I seem to recall having a similar issue with that disk, but didn't investigate it at the time. You might want to test the upstream libdvdnav/libdvdread, as a lot of fixes have gone into those lately, so there might already be a patch available. If so, and especially if you can help identify which patch is needed, that could help accelerate getting that fix into precise. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094499 Title: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdnav/+bug/1094499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1094499] Re: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters()
In playing with the IFO bdrung provided I found that the crash was caused by an out of bounds array access. The value was up in the 32,000's. I haven't sorted out why it's so high for this IFO, but am guessing it's either undefined data or bad pointer math. Potentially the bug is in libdvdread rather than in libdvdnav, but I only see the bad value in dvdnav code. Anyway, I stuck in a test to verify the value is in the 0 to 1000 range and skip processing if it isn't. That definitely prevented vlc from crashing. However since there was only the IFO provided, I can't tell if this resulted in a playable movie. I've stuck my debug packages for dvdnav and dvdread (which spit out a lot of values) into the following PPA. bdrung, why don't you give this a try with the full DVD copy. https://launchpad.net/~bryce/+archive/lp1094499 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094499 Title: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdnav/+bug/1094499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1094499] Re: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters()
@bdrung, Well, the stacktrace for this bug is only hinting at the problem, but I don't think other logs would explain what happened. It seems a pointer is getting set to an invalid value somewhere else in the program prior to the crash, but not clear how, when, or why. So I think the next step for this is to gather more data as to how this pointer is being changed through the life of the program. Attached is a debugging patch to print out some additional debugging info. Apply this patch to your build, repro the bug, collect the debug log leading up to the crash, and post that back here (or email it to me directly if it includes any private information). Make sure to doublecheck that you're getting the same crash (faulting in dvdnav_describe_title_chapters()). The value 0x25 seems intriguing to me; in decimal that's number 37, which seems like it could be the number of something. You might look and see if there's any 37's in the log output, or check if there are 37 chapters or something. Or, could be a red herring. Maybe also repro the crash three or four times and see if pgc is always 0x25 or if it varies from crash to crash. I'd also of course be interested in knowing what DVD causes this fault, and/or steps to reproduce the problem. I might be better able to figure this out if I can reproduce the fault locally. ** Patch added: pgc_debug.patch https://bugs.launchpad.net/ubuntu/+source/libdvdnav/+bug/1094499/+attachment/3642603/+files/pgc_debug.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1094499 Title: vlc crashed with SIGSEGV in dvdnav_describe_title_chapters() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libdvdnav/+bug/1094499/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This isn't the same as bug 934471, although the stacktraces are
deceptively similar. However, it seems to be crashing on a different
line, and for a different reason.
#0 0x7fb974591b16 in dvdnav_describe_title_chapters (this=0x7fb944001360,
title=title@entry=1, times=times@entry=0x7fb9704e2fd8,
duration=duration@entry=0x7fb9704e2fd0) at searching.c:653
retval = 0
parts = 29
pgc = 0x25
tmp = 0x7fb9440554a0
The code is:
pgc = ifo-vts_pgcit-pgci_srp[ptt[i].pgcn-1].pgc; // = 0x25
if (pgc == NULL) {
printerr(PGC missing.);
continue;
}
if(ptt[i].pgn pgc-nr_of_programs) { // 653: Crash!
So, it looks to me like this is an invalid pointer situation. Question
is how did it get set to 0x25 (37) in the first place?
