[Bug 27141] piglit glean/vertProg1 core dumps with RV790
http://bugs.freedesktop.org/show_bug.cgi?id=27141 --- Comment #2 from Chris Rankin ranki...@googlemail.com 2010-03-18 07:47:02 PST --- The problem happens when destroying the GLContext: - we call _mesa_free_context_data(), which sets ctx-DrawBuffer = NULL - _mesa_free_context_data() then calls _mesa_free_texture_data() - _mesa_free_texture_data() calls r600DeleteTexture() - r600DeleteTexture() calls radeonFlush() via radeon_firevertices() - radeonFlush() tries to dereference ctx-DrawBuffer, which has just been set to NULL - BANG! Adding a simple (ctx-DrawBuffer != NULL) check to radeonFlush() makes 43 of the vertProg1 piglit tests pass, with 2 failures: Program: RSQ test 2 (reciprocal square root of negative value) Expected color: -1, 0.1, 0.447, 1 Observed color: 0, 0, 0, 0 Program: LIT test 2 (degenerate case: 0 ^ 0 - 1) Expected color: 1, 0.65, 1, 1 Observed color: 1, 0.65098, 0, 1 -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.

http://bugs.freedesktop.org/show_bug.cgi?id=27141 --- Comment #4 from Chris Rankin ranki...@googlemail.com 2010-03-18 12:38:07 PST --- (In reply to comment #3) Patches are welcome :) Actually, I would describe this as the cause rather than the fix. I was hoping that someone who understands what the code *should* be doing would step in at this point. Maybe Mesa shouldn't be calling radeonFlush() in the first place here? Or maybe ctx-DrawBuffer shouldn't be unreferenced so early in the clean-up sequence? I have no intention of papering over this bug with an off-hand NULL check at this stage. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug. -- Download Intel#174; Parallel Studio Eval Try the new software tools for yourself.
