std::moneypunct not thread safe
-------------------------------
Key: STDCXX-453
URL: https://issues.apache.org/jira/browse/STDCXX-453
Project: C++ Standard Library
Issue Type: Bug
Components: 22. Localization
Affects Versions: 4.1.3
Reporter: Martin Sebor
Priority: Critical
Attachments: 22.locale.moneypunct.mt.html
The 22.locale.moneypunct.mt thread safety tests aborts at runtime indicating
that there is a thread safety issue in the locale implementation. Running the
test through the Intel Thread Checker reveals possible causes of the problem.
