SIGHUP in 22.locale.numpunct.mt
-------------------------------

                 Key: STDCXX-839
                 URL: https://issues.apache.org/jira/browse/STDCXX-839
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Tests
    Affects Versions: trunk
         Environment: Intel C++ 10.0
Red Hat Enterprise Linux Server release 5 (Tikanga)
            Reporter: Martin Sebor
            Assignee: Martin Sebor
             Fix For: 4.2.1


During nightly builds the test [22.locale.numpunct.mt.cpp|http://svn.apache.org/repos/asf/stdcxx/trunk/tests/localization/22.locale.numpunct.mt.cpp] times out on many platforms, including some build types with gcc 4.1 and all build types with Intel C++ 10/Linux, or with XLC++ 9.0 on AIX. The output below shows that it takes nearly 8 minutes to run to completion, which is in contrast to most other .mt tests which typically complete in less than 2 minutes. Since most of the locale thread safety tests follow the same pattern there must be some inefficiency either in the implementation of the {{std::numpunct}} facet or in specifics of the test itself (or both).

Since this test is new in 4.2.1, its failure is a regression.
