I'm using version 10.3.1-1 on Debian of most mesa-related packages and Linux kernel 3.18.0-rc1 from Linus' git head. replaying a particular dvd in VLC triggers some errors: (see also http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766058 ) vdpau-related packages are also installed; when I ran the dvd in VLC under valgrind I encountered: (comments are from michel@daenzer.net ) > ==13424== Invalid read of size 1 > ==13424== at 0x1A8789C0: r600_bind_blend_state_internal (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1A6723C0: blitter_restore_fragment_states (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1A675C47: util_blitter_clear_render_target (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1A852985: r600_clear_render_target (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1A69D9A9: vl_compositor_render (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1A629E96: vlVdpPresentationQueueDisplay (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1F2F80A3: Queue (in /usr/lib/vlc/plugins/vdpau/libvdpau_display_plugin.so) > ==13424== by 0x30D0E6DB48: ThreadDisplayPicture (in /usr/lib/libvlccore.so.8.0.0) > ==13424== by 0x30D0E6DEB2: Thread (in /usr/lib/libvlccore.so.8.0.0) > ==13424== by 0x30022080A3: start_thread (pthread_create.c:309) > ==13424== Address 0xedfe51d is 61 bytes inside a block of size 64 free'd > ==13424== at 0x4A08E90: free (vg_replace_malloc.c:473) > ==13424== by 0x1A62C7DD: vlVdpOutputSurfaceRenderBitmapSurface (in /usr/lib/x86_64-linux-gnu/vdpau/libvdpau_r600.so.1.0.0) > ==13424== by 0x1F2F8200: Queue (in /usr/lib/vlc/plugins/vdpau/libvdpau_display_plugin.so) > ==13424== by 0x30D0E6DB48: ThreadDisplayPicture (in /usr/lib/libvlccore.so.8.0.0) > ==13424== by 0x30D0E6DEB2: Thread (in /usr/lib/libvlccore.so.8.0.0) > ==13424== by 0x30022080A3: start_thread (pthread_create.c:309) This looks like a use-after-free bug in the Mesa r600g driver.
