You're just going to have to debug it. To start with, build with warnings, and look at them all. If none of that works and you're stuck, I'll have a look. This is unlikely to be a gcc bug. Does the upstream package segfault? Andrew. -- devel mailing list devel@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/devel
