Summary: double wcout.imbue crashes library

Initial Comment:
MinGW 5.1.3 (gcc 3.4.5), MSYS 1.0.10, STLport 5.1.4 Windows XP SP2.

g++ test.cpp  -Wall -mthreads -I/c/home/STLport-5.1.4/stlport/ -L/c/home/STLport-5.1.4/lib/ -lstlportg.5.1 -finput-charset=CP1251 -g

#include <iostream>

int main(int, char**)
{
	std::wcout.imbue(std::locale(".866"));	
	std::wcout << L"Hello world" << std::endl;
	std::wcout.imbue(std::locale(".866"));	
	std::wcout << L"Hello world" << std::endl;

	return 0;

./test 

It crashes with segmentation fault like:
