>Description:
libstdc++ was changed 2002-01-22 to use __convert_from_v to format numbers, and __convert_from_v basically does
setlocale "C"; sprintf; setlocale back
Unfortunately this is completely not thread safe, since all the other threads will change locales too, thus giving completely unpredictable results.
