--- Comment #33 from Benoit Jacob <[email protected]> --- The stack to the free() points to line 203 here, while the stack to where the free'd data is subsequently used points to line 205 here: http://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/nouveau_fence.c?id=ce6dd69697ae62d9336bbd4f5808bc4d75cdcc04#n203 if (fence == screen->fence.current) nouveau_fence_next(screen); do { nouveau_fence_update(screen, FALSE); // <--- free here! if (fence->state == NOUVEAU_FENCE_STATE_SIGNALLED) // <-- use-after-free return TRUE; So it seems like nouveau_fence_update (which was apparently inlined) destroys the fence object... do you need to call nouveau_fence_ref() to keep it alive? -- You are receiving this mail because: You are the assignee for the bug.
