--- Comment #37 from Iain Sandoe <iains at gcc dot gnu.org> 2011-10-17 18:28:47 UTC --- .. this doesn't fix the problem on Darwin9/m64 (with either the system libgcc_s or the one from current gcc/4.7). I suppose it's failing to unwind through the sigtramp - that might require some fiddling to solve.
