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.
