Subject [jira] Commented: (STDCXX-729) [HP aCC 6.15] warning #20200-D: potential null pointer dereference in _money_put.cc
Date Tue, 18 Mar 2008 20:37:24 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-729?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12580069#action_12580069
] 

Martin Sebor commented on STDCXX-729:
-------------------------------------

Looks like the fix committed in [r627612|http://svn.apache.org/viewvc?view=rev&revision=627612]
got reverted in [r631410|http://svn.apache.org/viewvc?view=rev&revision=631410] committed
to silence a (gcc?) warning...
