I believe this was fixed in master with commit: commit 4a72d859b4f8d0444eb7f38606d59d7ddc9ea8fa Author: Brian Paul <bri...@vmware.com> Date: Thu Feb 16 12:25:22 2012 -0700
util: add mutex lock in u_debug_memory.c code The linked list of memory allocations was not protected by a mutex. This lead to sporadic failures with multi-threaded apps. Reviewed-by: Jose Fonseca <jfons...@vmware.com> I've crossported to 8.0 branch. In general Mesa is thread safe, but I don't think it has received much testing with multi-threaded apps, so it's likely there are issues.
