Joel Jacobson managed to narrow it down to this test case, which crashes
consistently on Ubuntu 12.04 both with and without your patch. I,
however, wasn't able to reproduce the problem on my OS X Mountain Lion.
I'll try to get some more information about it tomorrow, but in the
mean time if you can reproduce the problem or think of something, I'll
post the test case.
