I ran your test case - with your implementation of _numpunct.h - and I even wrote a variant of it because I wanted to be able to test with more than one locale at a time: http://s247136804.onlinehome.us/stdcxx-1056-20120912/22.locale.liviu-1.mt.cpp They pass and they did not cause assertions. I initially had a concern about the case where two or more different threads ask for facet data on the same static locale object, ahd they happen to do so exactly at the same time. But there is a mutex in __rw_setlocale which will serialize this. Incidentally there are some optimizations which could be done in __rw_setlocale's constructor as well, along with the optimizations for the "C" locale in punct.cpp Martin mentioned yesterday. The performance of 22.locale.numpunct.mt is also much better with your _numpunct.h patch: real 668.93 user 804.00 sys 34.24 --Stefan -- Stefan Teleman KDE e.V. stefan.tele...@gmail.com
