It's a Windows Server 2008 thingy. MSFT added some code to the OS which checks for the validity of the SEH chain. The code is not compiled in to the client OSes, only to the Server OSes. We checked in a patch back in early 2008 to deal with this mechanism. That's probably the reason that the C testcase works fine. Apparently Perl adds something which makes the SEH chain invalid again from 2008's point of view. Btw., *everybody* can test on Windows Server 2008: http://www.microsoft.com/downloads/details.aspx?familyid=B6E99D4C-A40E-4FD2-A0F7-32212B520F50 Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Project Co-Leader cygwin AT cygwin DOT com Red Hat -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
