`noexcept` just stop the program while there is an exception
thrown in the function. It does not help.

On my Win7 VM (with GCC-4.7.1-tdm) the result is status 3.
Which version of GCC are you using? (I'm not sure why it's 255
on your machine).
This issue happens because libstdc++ doesn't support std::locale
on Windows. It just throw exception when you try to create a
non-"C" locale.
Liu Hao (CCed him) once said his (maybe modified) libstdc++
also support locale name "" (empty string). Maybe he can help
you.
There are some discussions about enhance generic locale code
with C89/C99 APIs. But there are many issues must be solved.
So libstdc++ still supports only "C" locale today. See
<http://gcc.gnu.org/ml/libstdc++/2003-02/msg00345.html>.
If we want to implement full locale support on Windows, and
w/o touching Windows internal undocumented APIs and legal
issues about Windows, we have to parse locale string
everywhere, and deal multi-thread things carefully.
If possible, I suggest you to use C89/C99 API directly. It's
more portable, but need more string parsing (locale strings
are everywhere in C89/C99 locale.h).
