Wow.  Is the behavior reproducible?  How about if you go ahead and
install, and do a plain "make installcheck" (or even just try a manual
createlang in a fresh database)?

That code thinks it is dealing with a concurrent index root page split,
but there couldn't be any concurrent operations happening during the
create-plpgsql step of a regression test run.  Can you step through
_bt_getroot() (it's in src/backend/access/nbtree/nbtpage.c) and figure
out exactly how it's getting confused?

If the behavior is reproducible I'm inclined to suspect a compiler bug;
it's hard to see how _bt_getroot could get so confused otherwise.
