--- Comment #3 from Jason Merrill <jason at gcc dot gnu.org> ---
The problem is that non-C++ exceptions like forced unwind have no exception
header, so we can't chain them onto caughtExceptions.  But it seems to me that
we ought to be able to wrap such an exception in a C++ exception to make it
more palatable to the C++ runtime: in __cxa_catch, we can allocate a C++
exception using the foreign exception as the object.  Anyone see a problem with
this strategy?
