vlc segmentation fault on linux 64 bit. happens when loading certain file types
VLC gives a segmentation fault when loading certain video file types. I've noticed mp4s, and some avis for certain. It's from a git build uname -a for my system: Linux hostname 3.2.0-2-amd64 #1 (closed) SMP Mon Jun 11 17:24:18 UTC 2012 x86_64 GNU/Linux
configure for the build: ../configure --enable-xvideo --enable-sdl --enable-avcodec --enable-avformat --enable-swscale --enable-mad --enable-a52 --enable-libmpeg2 --enable-dvdnav --enable-faad --enable-vorbis --enable-ogg --enable-theora --enable-mkv --enable-freetype --enable-fribidi --enable-speex --enable-flac --enable-live555 --enable-caca --enable-skins --enable-skins2 --enable-alsa --enable-qt4 --enable-ncurses --enable-x264 --enable-libva --enable-dxva2 --enable-libmpeg2 --enable-vorbis
