Well, that's pretty darn odd.  It looks like you could work around the
crash by setting superuser_reserved_connections to 0, but that doesn't
tell us *why* it's crashing.  HaveNFreeProcs, and the data structure
it looks at, are simple enough that it's hard to credit a bug there.
I'm worried that what you've got is really a compiler bug.  What
compiler did you build with, and did you use any nondefault CFLAGS?
(pg_config output would be helpful here.)
