[jira] Commented: (STDCXX-1043) [Como como 4.3.10.1] std::cout << std::endl cayses SIGSEGV on Linux

    [ https://issues.apache.org/jira/browse/STDCXX-1043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12752608#action_12752608 ] 

Martin Sebor commented on STDCXX-1043:
--------------------------------------

Does an unoptimized non-reentrant build (11s) work? We use EDG eccp only for conformance testing; optimization or thread safety might have problems, shared library builds are known not to work at all.
