Is there a particular gcc bug you traced it down to? Because it does not follow that all changes to program behaviour with different optimization options are necessarily gcc bugs; it can show up broken-ness in code that happens to not show symptoms according to how it is compiled. -Andy _______________________________________________ arm mailing list arm@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/arm
