The answer depends on what you understand under "unhandled exception"
and what you want to do in such a state.
In practice such things have little use. Side effects of unanticipated
[language and then system] exception propagation tend to ruin any
relevant information and data so that at the point when the handler is
called everything is in a total mess.
The best way I know is tracing exceptions. With GNAT you can quite
easily hook up exception raising points when some useful information is
still there.
