Well, that sucks.  I just started putting together commits for 7.8
recently, specifically because I/we need *that* one commit ;)

Is your test multithreaded, by any chance?

It looked like some sort of strange link/memory corruption to me
before, but valgrind didn't turn up much, and this commit really does
so little; it seems odd to blame memory corruption in this case.
Brian, any ideas?
