[Mesa-dev] Minecraft crash in nouveau_dri.so

[Ilia Mirkin]

The relevant code:

   if (slab->free == 0) {
      LIST_DEL(&slab->head);
      LIST_ADD(&slab->head, &bucket->full);
   }

And the LIST_ADD is line 206 (on the 9.2 branch).

Do you know if multiple GL threads are used? I looked at the code, and
it seems perfectly fine, and hasn't changed in forever
(nouveau_mm_allocate is still the same in 10.2-git). Unless there are
multiple threads that are each doing allocations, in which case,
ka-boom. (In general, nouveau is not safe with simultaneously-running
threads, even if they have separate GL contexts... yet. I've started
looking at it, but there are a lot of pieces to the puzzle.)
