Just to be completely clear: What's happening here is that that remote_elem
pointer is _never_ getting initialized. Even in the cases where this was
"working" on some machines... it was just because that un-initialized
memory for remote_elem was non-zero... so it wasn't tripping the assert.
With Parallel mesh it was probably failing spectacularly the first time
you tried to access that remote_elem.
