I now realize that you must have been using the latest binutils, as the
old one silently generated bad unwind info.

As Richard pointed out in his mail, the offending code really is
broken.  I was planning to update the mozilla libffi anyhow, both to
sync up with Hans's recent unwind fixes and to look into whether we
could use the assembler directives added for C++ vtables to simplify
the generation of static closures.  Let me take a look at it.
