Looking again, the pg_regress output appears to indicate two separate
crashes (one during rangetypes, the other during create_index).  The
reported Assert trap was in the rangetypes test, but the other one
could very easily have been from spgist code as well.  I'd tend to
write off all the other reported diffs as followon damage from the
crashes, at least without clearer evidence that they weren't.  There are
very many instances in our regression tests where failure to complete
one test results in bogus diffs in later ones, because DB objects don't
exist or don't have the expected contents.
