[jira] Commented: (STDCXX-450) std::use_facet() not thread safe

    [ https://issues.apache.org/jira/browse/STDCXX-450?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12531542 ] 

Farid Zaripov commented on STDCXX-450:
--------------------------------------

I can't to reproduce this bug on MSCV 8.0 and gcc 4.2.0/Linux. Perhaps the bug accidentally fixed while fixing the another mt bugs (i.e. numpunct<>).

> The 22.locale.num.put.mt thread safety tests aborts at runtime indicating that there is a thread safety issue in the locale implementation. Unfortunately, running the test through the Intel Thread Checker hasn't revealed the cause of the problem since the thread checker exits prematurely, most likely due to a bug in the tool itself (see below).
