Minor Description
Running many of the locale tests with the '--help' command line argument results in an assertion error and then immediate program termination. This makes it difficult to tell what command line options are available. A test that shows this problem is 22.locale.time.put.mt.cpp.
This is because the rw_opt_setlocales function in locales.cpp doesn't handle the case where the first argument is NULL. This is the case when the --help command line argument exists. Most of the other rw_opt_... methods have a test like this near the top of the file.
if (1 == argc && argv && 0 == argv [0]) {
}
If the test passes, argv[0] will be set to the help string that should be used.
