If you are using ansi prototype style for your function definitions
(manditory in C++) then it is possible that you may eventually come
across a prototyped function definition in which one or more of the
formal parameter names have been left out.  For example:

void quiet_File_error_handler(char*)
{
  errno = 0;
}

The example above comes from libg++ (1.36.1).  This is legal ansi (and C++)
but if you are using GCC 1.36 or G++ 1.36.1 with COFF and using -g, you
will get cc1 (or cc1plus) segfaulting on the example shown above.

The fix is simple, and is provided below.  (Your line numbers may vary.)

Enjoy,
