I wonder why the following code throws std::runtime_error
even though the LC_ALL is set to valid locale other than "C".
This does not occur only when LC_ALL is set to "C".

#include <locale>
int main()
{
	std::locale("");
	return 0;
}

In linux, this occurs only when the LC_ALL is set to invalid
locale (i.e. locale that is not registered in system).

Any idea?
