May be finally I will indeed not report a bug, as it seems this bug has already been reported on April 2004, with GCC 3.4.1. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14925 It is said a patch was released, so may be that's not exactly the same bug, but the “come‑back” of a similar bug. Anyway, that may be a good starting point to study the issue. -- View this message in context: http://gcc.1065356.n5.nabble.com/Inconsistant-exception-API-libgcc-s-and-cc1-don-t-agree-tp931332p931395.html Sent from the gcc - Help mailing list archive at Nabble.com.
