Mark, you know what I'm going to ask ;)  Is this OK for 3.4.1?  Or should
it wait until 3.4.2?

Perhaps the patch isn't quite as obvious as the one you approved earlier
today.  But IMO it _is_ still obvious.  And safe.  The bug here is also
much more serious, since it only shows up at run time (rather than
link time).

I suppose every patch carries some amount of risk.  But like I say,
I think the risk in this case is very small, and I think it's obvious
that the new code is theoretically more correct.  From that POV,
I'd imagine the risk is more of introducing an ICE than introducing
another wrong code bug.

Err... couldn't decide whether to delete that last paragraph or not ;)
