--- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm, somehow I remember reports similar to this on Darwin.  Can you try using
clang for bootstrap?

What X-Code version are you using on which OS version?

The crash reporter suggests sth goes wrong with linking as it seems to crash
during init already.
