Comment (by ken-cunningham-webuse):

 OK. Learning about gdb, etc. here's what happens when trying to run the
 ./test_throw program on 10.5 leopard Intel compiled with clang-3.7, libcxx
 3.9.0, libcxxabi 3.9.0, and libunwind 3.9.0

 this certainly looks like a bug to my untrained eyes. malloc is trying to
 allocate a huge amount of memory.
 I'll post the whole gdb log as an attachement -- K
