--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
This happens in libsupc++/eh_personality.cc set the thrown type to
__forced_unwind:

      // During forced unwinding, match a magic exception type.
      if (actions & _UA_FORCE_UNWIND)
        {
          throw_type = &typeid(abi::__forced_unwind);
        }
