Subject [jira] Updated: (STDCXX-842) [XLC++ 7.0, 8.0] SEGV in 22.locale.codecvt.out
Date Wed, 09 Apr 2008 17:19:26 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Travis Vitek updated STDCXX-842:
--------------------------------

       Regression: [Regression]
      Description: 
On AIX, when compiled with XLC++ in 64-bit mode with optimization on, the test [22.locale.codecvt.out.cpp|http://svn.apache.org/viewvc/stdcxx/trunk/tests/localization/22.locale.codecvt.out.cpp?view=markup]
fails with {{SIGSEGV}}.

Since this test is actually being compiled for the first time in 4.2.1, its failure is a regression.
