             Summary: numpunct facet cache initialization is not thread -safe
                 Key: STDCXX-1071
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 22. Localization, Thread Safety
    Affects Versions: 4.2.1, 4.2.x, 4.3.x, 5.0.0
         Environment: $ uname -a; CC -V
Linux behemoth #3 SMP Sat Apr 9 22:49:32 CDT 2011 x86_64 AMD Opteron(tm) Processor

The bug affects the initialization of the cached data in numpunct facet. The failing test
is 22.locale.numpunct.cpp in certain builds: Linux with SUNPro 5.12, optimized, most likely
to fail. It has been reported (see linked incidents) to fail on SPARC as well. It manifests
in variate ways: sometimes as heap corruption, sometimes as access violations, etc. Test cases
and library reduction programs to follow.
