I agree that a dirty build seems like a reasonable explanation, but it
doesn't seem to be the case here. I did distclean, bootstrapped and
re-configured, and I tested a bunch of libMesh examples and they all worked
fine. But with this negative-jacobian test, l still got the same segfault.
I can send you the test code to see if you hit the same error?

It may be something similar. Though TET10's from CUBIT are used a lot, and
I haven't had any problems with it before, so I'd be surprised if that was
the case.
