<<I have made a little patch to a-raise.c so __gnat_unhandled_exception
unwinds the stack and writes all return addresses to stderr. This
works without any problems and I was surprised how easy this was
to do.

Sorry, this just does not work, in the general case, when control
is passed to __gnat_unhandled_exception is called, the stack has
already been completely destroyed.

yes it will work in trivial cases with no exception frames around,
that is probably what is confusing you.
