SIGHUP in 22.locale.numpunct.mt

• Key: STDCXX-839
• Type: Bug
• Status: Open
• Priority: Major
• Assignee: Unassigned
• Reporter: Martin Sebor
• Component/s: Tests
• Affects Version/s: 4.2.1
• Fix Version/s: 4.2.2

Environment

Intel C++ 10.0
Red Hat Enterprise Linux Server release 5 (Tikanga)

Description

During nightly builds the test 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.
