std::numpunct not thread safe
-----------------------------
Key: STDCXX-452
URL: https://issues.apache.org/jira/browse/STDCXX-452
Project: C++ Standard Library
Issue Type: Bug
Components: 22. Localization
Affects Versions: 4.1.2
Environment: all
Reporter: Martin Sebor
Priority: Blocker
Attachments: 22.locale.numpunct.mt.html
The 22.locale.numpunct.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.
$ tcheck_cl -v && make 22.locale.numpunct.mt && tcheck_cl -f html -o
