I tested it myself (along with all the other -m32 cases on Mac), although I didn't even know I had /usr/bin/clang on 10.6 and 3.2.6.
I did not look at the assembly of all the cases; the bus error on close() was my definitive check, along with I *think* testing the stupid asm("") thing. I'm on my phone right now so I can't be sure.
I haven't tested 10.8 at all, so those are from other user reports.
