Indeed!

template< typename E >
void f14(coro_void_void::caller_type & , E const& e)
{
   boost::throw_exception(e);
}

works as expected.

Oliver suggested:

boost::throw_exception(boost::enable_current_exception(e));

As the previous gives me the expected behavior(at least on the surface), 
I'm not sure what this latter provides even after a quick read of the docs.

Thanks, Jeff
