I think doing something like

void cplusplus_call(void * code, void * args)
{
   // I've no idea about C++ exception syntax, but you get the idea
   try {
     return code(args);
   except {
     return convert_to_lisp_condition(code, args);
   }
}

might work, but this glosses over huge amounts of hair -- it does avoid 
the arcane manipulations by punting them to the C-compiler, though. ;-)

Cheers,
