--- Comment #32 from D. Hugh Redelmeier <hugh at mimosa.com> ---
Thanks, Knut, for bisecting in #27.  Thanks, Stan, for confirming bisection in
#28.

So the bad changeset is
http://cgit.freedesktop.org/mesa/mesa/commit/?id=35840ab189595b817fa8b1a1df8cc92474a7c38d

I read that code (out of context: I'm not familiar with Xorg code).  It kind of
looked as if things with obvious allocation potential were followed by asserts
to check that the allocation worked.  So why are we observing SIGBUS rather
than assertion errors?  If allocation failure is possible, even assertion
failure seems harsh (but at least more diagnostic).
