The patch is problematic in several ways:

 * nsub is an optional argument; its absence is not an error.
 * The if branch you are patching doesn't actually use nsub; only the
   first three arguments are passed to old_main().
 * From a cursory gdb session, the reason crashme segfaults is that it
   executes illegal instructions, not in the options parsing.

Thanks,
