std::use_facet<std::num_put>() not thread safe
----------------------------------------------
Key: STDCXX-450
URL: https://issues.apache.org/jira/browse/STDCXX-450
Project: C++ Standard Library
Issue Type: Bug
Components: 22. Localization
Affects Versions: 4.1.3, 4.2
Environment: Linux
Reporter: Martin Sebor
Priority: Blocker
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).
