Travis Vitek updated STDCXX-571:
--------------------------------

    Attachment: 22.locale.numpunct.mt.cpp

2007-09-26  Travis Vitek  <vitek@roguewave.com>

	STDCXX-571
	* 22.locale.numpunct.mt.cpp (run_test): Use C++ locale to
	generate test data. This is to avoid any incompatibilities
	between C and C++ locales.
	(thread_func): Updated to use changed test data types.

> The current numpunct.mt test fails on at least one platform because the initialization
code and the test code use two different methods for retrieving the numpunct data. The run_test
function uses std::localeconv(), and thread_func uses the C++ locale numpunct facet. In most
situations this isn't a problem.
> Unfortunately, due to incompatibilities between the C and C++ locale details, the thousands
seperator is different with the "C" locale. For C++ it is ',' and for C it is the empty string.
Here is a quick test to show the problem that the test sees.
> #include <clocale>
> #include <locale>
> int main()
> {
>     if (!std::setlocale (LC_ALL, "C"))
>         return 1;
>     const std::lconv* const pconv = std::localeconv ();
>     // test against the specialization directly
>     const std::numpunct<char> np(0);
>     assert (*pconv->decimal_point == np.decimal_point ());
>     assert (*pconv->thousands_sep == np.thousands_sep ());
>     return 0;
> }
> The test should be enhanced to use the C++ locale for both run_test and thread_func.
