Agreed. By the time that stacktrace was taken, the underlying bug had done its damage. That's why I asked (comment #11) for an additional backtrace from _mesa_problem. Something is causing the driver to create a DEPTH_COMPONENT24 texture, but that hardware doesn't support depth textures at all. As a result, by the time execution gets to _mesa_get_format_bytes or intel_region_alloc, it's passing around garbage data. In the intel_region_alloc case, the texture format is unknown to the driver, so cpp is zero. The divide by cpp causes the SIGFPE. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- 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
