Let me know if the patch doesn't apply. Also could try deleting your ~/.dvdcss and ~/.dvdnav folders one at a time, see if that helps [?] On Sun, Aug 17, 2014 at 9:16 AM, Michael Russo <greatquux@gmail.com> wrote:
Not sure if the patch would help or if it's applicable to version 5 or has to be rebased. But I know this DVD was extracted perfectly and plays on DVD players. Same issue playing directly from DVD drive in VLC (which uses libdvdnav of course). Main title plays in mplayer. I'll see if I can get a Windows system or VM to play it there or maybe use a DVD shrinker on it (but that will probably just copy the titles/menu/nav stuff anyway).

looks like it's definitely infinitely recursing to me.
I seem to recall some ancient patch that mentions ref counts something, wonder if that's related...
http://lists.mplayerhq.hu/pipermail/dvdnav-discuss/2012-December/001816.html
re-proposed once here http://comments.gmane.org/gmane.comp.video.dvdnav.general/1658
[BTW does that patch have merit, even if unrelated, I wonder?]

That did help and I was now able to compile libdvdnav with TRACE defined. I still ran vlc through gdb in order to get a backtrace. There was a LOT of tracing going on, and now the SIGSEGV occurred inside of printf() because it was trying to print out the invalid memory address. Hopefully there's something here you can use to track down what's going on. It's likely some weird form of copy protection.

I tried to define TRACE in vm.h (uncommenting the line) but I get a message about an undefined constant FP_DOMAIN. The compilation succeeds without TRACE enabled. I also can't find where this constant is defined inside of libdvdnav. Perhaps this is a simple oversight related to all the cleanup work that took place in 5.0.0?
Actually, it was probably related to an earlier commit. See:
http://git.videolan.org/?p=libdvdnav.git;a=commitdiff;h=331781f98a8ea6842bee...
I updated the constants just now:

I also cleaned up some compiler warnings in my earlier checkin that I didn't notice before. Sorry about that.
