Bug 124799 – xine crashes on random events.

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description George Prowse 2006-03-03 07:01:02 UTC]

this is similar to bug #96073 but that seemed to be a hardened issue.

xine crashes at certain points, opening certain files or being started through gdb but at other times it is fine. I would think it is a library issue but mplayer opens everything without trouble. Here is the gdb dump:

This GDB was configured as "x86_64-pc-linux-gnu"...(no debugging symbols found)
Using host libthread_db library "/lib/tls/libthread_db.so.1".

(gdb) run
Starting program: /usr/bin/xine

The backtrace you're pasting is not useful, as it's just a real time event. Please try rebuilding xine-ui and xine-lib with -ggdb in CFLAGS and splitdebug, then use ulimit -c unlimited to get a core dump, when you have that, paste the output of "bt" command after launching gdb as "gdb `which xine` --core core.<pid>".

When you'll have something I can work on, please reopen.

StubbornAesthetics ~ # FEATURES="splitdebug" CFLAGS="-ggdb" emerge xine-lib xine-ui

I assume that's what you mean by the first part. Did that - and everything went smoothly. What do you mean by running "ulimit -c unlimited" to get a core dump? ulimit doesn't have a -c option, according to its man page.
