Subject [jira] Commented: (STDCXX-369) [gcc 3.2.3-56/Linux] ld errors on hidden symbol _Unwind_GetIPInfo
Date Fri, 23 Mar 2007 19:23:32 GMT

    [ https://issues.apache.org/jira/browse/STDCXX-369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12483717
] 

Martin Sebor commented on STDCXX-369:
-------------------------------------

Interestingly, gcc 3.2.3-53 doesn't have this problem, and neither does Intel C++ 9.0 (9.0.31
to be exact) when when sitting on top of the gcc with the hidden symbol. So it seems to be
specific to gcc 3.2.3-56.
