Sorry, I understood that wrong. I thought Eric reported the bug that installing the libsigsegv *stack overflow* handler corrupted the cygwin SEH chain with Win2008. Not the *segv* handler. But then I learned that indeed a Win2008 exception causes another SEGV to be delayed (http://lists.gnu.org/archive/html/bug-gnulib/2009-07/msg0009= 2.html) and this fools the segv handler, not the stack handler. --=20 Reini Urban http://phpwiki.org/ http://murbreak.at/ -- 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
