Subject [jira] Created: (STDCXX-503) std::ctype not thread safe
Date Mon, 30 Jul 2007 00:31:52 GMT
std::ctype not thread safe
--------------------------

                 Key: STDCXX-503
                 URL: https://issues.apache.org/jira/browse/STDCXX-503
             Project: C++ Standard Library
          Issue Type: Bug
          Components: 22. Localization
         Environment: Intel C++ 10.0 20070613 on Linux/EM64T
            Reporter: Martin Sebor


The 22.locale.ctype.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.
