Well, was worth a try, although the stack trace didn't look very close
to any of the GIN or hot-standby fixes that I can remember offhand.

Not sure what to make of it. If the stack trace can be believed,
it's crashing in one of the memsets in ReadBuffer_common() ... which
ought to be impossible, because they're fixed-length and always pointed
at a buffer.

It might be worth recompiling at -O0, first to see if that changes the
behavior and second to see if it changes the reported stack trace.
