[Mesa-dev] [Bug 74251] Segfault in st_finalize_texture with Texture Buffer
https://bugs.freedesktop.org/show_bug.cgi?id=74251 --- Comment #9 from Ian Milligan ianml...@gmail.com --- It appears that loading a shader which expects a texture buffer causes the first texture unit's target to be set to TEXTURE_BUFFER. When st_validate_state is called without a texture bound to this texture unit, st_validate_texture is called on this texture unit's texture object. However st_validate_texture expects a texture object with target TEXTURE_BUFFER to have defined the field BufferObject, causing the null pointer dereference. Unfortunately, I'm not sure where the fault lies here. -- You are receiving this mail because: You are the assignee for the bug. ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev

https://bugs.freedesktop.org/show_bug.cgi?id=74251 --- Comment #8 from Ian Milligan ianml...@gmail.com --- The segfault appears to occur when glClear is called while a vertex shader expecting a texture buffer is loaded, but no texture is bound. This can be reproduced simply by loading the attached vertex shader and calling glClear. -- You are receiving this mail because: You are the assignee for the bug. ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
