--- Comment #1 from Zoltan Herczeg <hzmester@???> ---
I am not sure exception handling is standardized, I think most compilers have
freedom to do it their own way.

However, you can instantly return from a callout, so this could work: capture
the exception by your callout handler, store the exception value temporarily
somewhere, and abort the match. When a match returns with abort, re-throw your
exception.

You can also use the interpreter as you mentioned.
