I added some print statements to the test code I was running before (with
libMesh git hash 1a6a549f26219f462ac4ceef87c3c03e9eafa836) and I get the
info printed below for the failing element.
When I update to the git HEAD, I now get a segfault with no stack trace
when I just loop over the elements and call fe->reinit(elem). I'm wondering
if maybe ExodusIO isn't reading this mesh in properly, or something.
