BTW, looking closer, I think that the pg_regress output is telling us
that it's psql that is segfaulting, not the backend.  I wonder whether
the cause could be the refactoring that Noah did to move some quote
processing functionality into src/fe_utils/.  In this theory, the reason
why your build is failing and nobody else's is could be that you're
somehow linking to an obsolete version of libpgfeutils.a, causing a
missing-symbol error (which Linux is not good about complaining about
at link time).
