Subject [jira] Updated: (STDCXX-464) [HP-UX 11.23] std::num_put drops sign from negative long double NaN
Date Thu, 23 Aug 2007 15:58:30 GMT

     [ https://issues.apache.org/jira/browse/STDCXX-464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Martin Sebor updated STDCXX-464:
--------------------------------

             Priority: Minor  (was: Major)
    Affects Version/s: 4.2
        Fix Version/s: 4.2.1

This will be hard to fix given that it's caused by a compiler bug. Lowered Priority and deferred
to 4.2.1.
