> 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.
