Looks fine to me too ... I wish I'd seen this 30 seconds ago.
I literally just hit this bug on mac and filed a dup (which I'll close)
and then saw this RFR.

BTW What I'm trying to do is see the gcc compiler options that
are actually used on Mac. debug and info options didn't
reveal anything. What should I use ?
