I don't think so; I think try/catch are a better way to get a handle on the
exception object.  When I started writing a verbose terminate handler,
originally I was trying to hand the object pointer from the EH structures
off to the dynamic cast machinery by hand to get an exception*, until I
realized that I could just write

  try { throw; }
  catch (exception& e) { ... }
  catch (...) { }

which is both simpler and portable.
