$ clang++-mp-3.7 -stdlib=libstdc++ -arch ppc test_throw.cxx
ld: warning: 32-bit absolute address out of range (0x100001ED8 max is 4GB):

Attaching output of:

$ g++-apple-4.2 test_throw.cxx -arch ppc -S -o test_throw.gcc.s

Also an issue with 3.8. I just wasn't using it for other reasons at the time:
$ clang++-mp-3.8 -stdlib=libstdc++ -arch ppc test_throw.cxx
ld: warning: 32-bit absolute address out of range (0x100001ED8 max is 4GB):
from GCC_except_table0 + 0x00000048 (0x00001F4C) to 0x100001ED8

3.9+ fail to build on Leopard at the moment, so I haven't tried them yet, but I
doubt this issue is fixed in newer builds.
