[jira] Commented: (STDCXX-847) [XLC++ 7,8,9] SEGV in
22.locale.time.get
[ https://issues.apache.org/jira/browse/STDCXX-847?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12594415#action_12594415 ]
Travis Vitek commented on STDCXX-847:
-------------------------------------
One possible workaround would be to write a utility to capture the locale data and write it out to a file in $(BUILDDIR). Then the {{rw_locales()}} and {{rw_query_locales()}} functions could just load up this file and read the data from there.
