Hi, I've tried to fix the broken zorba package in rawhide for a couple of weeks now but, unfortunately, without much success. The upstream developers don't seem to be able to find the cause for the issue either. The problem is that the package fails to build with gcc 4.9.0 (all archs) because the generated zorba binary segfaults for some queries due to accessing already freed memory. The issue only occurs with optimized builds (-O1, -O2, -O3) using gcc 4.9.0. With gcc 4.8.x the binary and thus the whole package build and work correctly. Therefore, it might also be possible that there's a bug in gcc's optimizer, but I'm not sure. valgrind and gcc's address sanitizer report the code sections where the error occurs but when stepping through them with a debugger, I'm unable to understand what's actually going on there. It looks as if the affected code should work properly. So I got stuck now. It would be great if someone could help to track down the issue in order to keep the package available in Fedora. Here is the latest SRPM: http://mgieseki.fedorapeople.org/review/zorba-3.0.0-4.fc21.src.rpm The corresponding bug tickets can be found here: https://bugzilla.redhat.com/show_bug.cgi?id=1095292 https://bugs.launchpad.net/bugs/1317976 Thanks, Martin
Does it happen if you compile it *with* -fno-delete-null-pointer-checks switch? That one caused a lot of grief with BIND 9. -- Petr^2 Spacek -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
