maybe some DWARF unwind tables are not correctly installed in OS X?

Hi Gabor, thanks, I will look into that.

Do intra-C++ exception catching work in your example?

Yes, I have a C++ executable foo[1] that links with libfoo that correctly catches the exception:

$(nix-build --no-link -A foo)/bin/test ... Whoops!

Since it's working in pure C++ I suspect it has something to do with how GHC calls either the C++ compiler or linker.
