Ah ha! After some pretty intense studying, looks like libunwind gives enough information for us to distinguosh which thrown objects should be stringed together. All what I think is needed is for gdc to emit some __begin_catch call which builds and returns the constructed Exception object to be passed to user-land. Regards Iain.
