Hi Gabor, thanks, I will look into that.

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.
