FWIW, there is a similar issue with the Mercury front-end,
where we want bug reports directed to a different mailing address.
That's the only change in the ICE message we need,
but to implement this we end up duplicating a few lines
of code to report the diagnostic.  This wouldn't be much
of a problem, except that those few lines of code seem to
change quite often.  To be honest, though, if the cure for
this duplication involves changing the front-end interface
then I'd say the cure would be worse than the disease.

static void
merc_handle_internal_error (msg, args)
  const char *msg;
  va_list *args;
{
  diagnostic_info diagnostic;

  diagnostic_set_info (&diagnostic, msg, args, input_filename, lineno,
                       DK_ICE);

  report_diagnostic (&diagnostic);

  fprintf (stderr,
  	   "Please submit a full bug report to <mercury-bugs@cs.mu.oz.au>.\n");
  exit (FATAL_EXIT_CODE);
}
