Hi, I've been playing around a bit with VLC (after compiling world, and all my pkgsrc with debugging symbols). The testing machine is a VM so I access to it via ssh. I've installed all the needed packages to be able to forward X to my local display. So, I've run VLC in my local display and it does segfault after closing, just like always. As I got a non-meaningful backtrace, I decided to run it from my gdb. It segfaults again! It doesn't even show any window and this is the backtrace: (gdb) bt #0 0x28179c5c in _umtx_sleep_err () at/home/source/dfbsd/lib/libthread_xu/arch/i386/i386/_umtx_sleep_wakeup_err.S:12 #1 0x2817998c in _thr_umtx_wait (mtx=0x282f6adc, exp=0, timeout=0x0, clockid=0) at /home/source/dfbsd/lib/libthread_xu/thread/thr_umtx.c:131 #2 0x281748c3 in cond_wait_common (cond=<value optimized out>, mutex=0x282a7df0, abstime=0x0, cancel=1) at /home/source/dfbsd/lib/libthread_xu/thread/thr_cond.c:230 #3 0x28174a41 in __pthread_cond_wait (cond=0x282a7df4, mutex=0x282a7df0) at /home/source/dfbsd/lib/libthread_xu/thread/thr_cond.c:264 #4 0x2911dfd9 in QWaitConditionPrivate::wait (this=0x288ad6a0, mutex=0x288ad69c, time=4294967295) at thread/qwaitcondition_unix.cpp:87 #5 QWaitCondition::wait (this=0x288ad6a0, mutex=0x288ad69c,time=4294967295) at thread/qwaitcondition_unix.cpp:159 #6 0x2870a50e in Open (p_this=0x28321208) at qt4.cpp:307 #7 0x28126da2 in __module_need (p_this=0x28321208,psz_capability=0x28159a40 "interface", psz_name=0x282e3d70 "", b_strict=true) at modules/modules.c:580 #8 0x280c7f27 in __intf_Create (p_this=0x282c00b0,psz_module=0x281512e0 "$intf") at interface/interface.c:104 #9 0x280b3085 in libvlc_InternalAddIntf (p_libvlc=0x282c00b0,psz_module=0x1d5 <Address 0x1d5 out of bounds>) at libvlc.c:1176 #10 0x2808b775 in libvlc_add_intf (p_i=0x28300080, name=0x0,p_e=0xbfbff86c) at control/core.c:188 #11 0x08048e57 in main (i_argc=1, ppsz_argv=0xbfbff8e0) at vlc.c:153 It seems it hits another segfault in initalization, but well, I still wanted to find out the backtrace after a the crash while closing. So I started VLC again and then attached with gdb. The issued 'cont' in gdb, went to VLC window and closed it. This time there's a weird error. See the backtrace: Program received signal ?, Unknown signal. 0x281ea323 in lwp_kill () at lwp_kill.S:2 2 RSYSCALL(lwp_kill) (gdb) bt #0 0x281ea323 in lwp_kill () at lwp_kill.S:2 #1 0x28177b14 in _thr_send_sig (thread=0x28290af0, sig=32) at /home/source/dfbsd/lib/libthread_xu/thread/thr_kern.c:99 #2 0x28176acf in _pthread_cancel (pthread=0x28290af0) at /home/source/dfbsd/lib/libthread_xu/thread/thr_cancel.c:64 #3 0x2812cfeb in vlc_cancel (thread_id=0x28290af0) at misc/threads.c:941 #4 0x280ce07f in playlist_preparser_Delete (p_preparser=0x28306ea0) at playlist/preparser.c:97 #5 0x280c8955 in playlist_Deactivate (p_playlist=0x283309c0) at playlist/thread.c:101 #6 0x280b4a2f in libvlc_InternalCleanup (p_libvlc=0x282c00b0) at libvlc.c:1036 #7 0x2808b651 in libvlc_release (p_instance=0x28300080) at control/core.c:179 #8 0x08048e8b in main (i_argc=1, ppsz_argv=0xbfbffb98) at vlc.c:156 I hope this throws a bit more light into this.
