Ugh. I was in 10.7.5, just tried in 10.8.2 and seems someone has already fixed this.
Anyway, I think it's a nice example of why fine-graned control over -fcatch-undefined-behavior would be nice: enabling it can find bugs that you can't fix. If I could turn off the unaligned memory check, at least I could proceed and maybe find some bugs in my own code...
Thanks to all for helping.
