Stl_unit_test hangs on startup for Ukrainian locale

I'm using Visual Studio 2003 and Stlport 5.1.1 on WinXP SP2.
I've built the stlport dlls and stl_unit_test executables using default settings.
Both debug and release versions of stl_unit_test hang without any output.
Debugging shows that it runs into an unfinite loop on initializing a locale.

Call stack is below. Note the value of NTDate. It ends with ' p.' which is Ukrainian abbreviation for "year". Most probably it's the reason for the infinite loop.
