*** Bug 749015 has been marked as a duplicate of this bug. *** Fwiw, all those referenced demos are ok on my f14/x86_64 box. Created attachment 530276 [details] Qt Creator backtrace by Slawomir Czarko I extracted the backtrace of the relevant thread from: https://bugzilla.redhat.com/show_bug.cgi?id=749015#c1 I can reproduce the crash in the calculator demo (not tested the others nor Qt Creator yet) with qt-x11-4.7.4-2.fc15.i686. The backtrace appears to match the Qt Creator one, but I haven't installed qt-x11-debuginfo yet, so there's a lot of information missing, and so I can't tell for sure. Hit the same issue and I can confirm it's ok within Qt SDK (upstream Qt build) so it has to be something in our packaging or g++/whatever issue. KAN EYE HAZ VALGRIND LOGZ PLZ LOL??????????!!!!!!!!????????????? [insert picture of cute kitten here] ;-) According to upstream's bug report (one of duplicates), -O2 -fno-strict-aliasing is working workaround. Right, according to the upstream tracker, this is an aliasing issue. Found a couple of aliasing problems, once we looked closer, %changelog * Thu Nov 03 2011 Rex Dieter <rdieter> 1:4.7.4-6 - build declarative/qml with -fno-strict-aliasing (#748936, QTBUG-19736) - build tds sql driver with -fno-strict-aliasing Build queue'd: http://koji.fedoraproject.org/koji/buildinfo?buildID=272173 qt-4.7.4-6.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/qt-4.7.4-6.fc15 Package qt-4.7.4-6.fc15: * should fix your issue, * was pushed to the Fedora 15 testing repository, * should be available at your local mirror within two days.
