gcc version 13.2.0 (Ubuntu 13.2.0-23ubuntu4) seems to remove some code in release builds that is embedded in a macro in qtransfrom.cpp. This patch changes the macro into a function such that it is not removed by gcc. It seems like the switch statement is (wrongly) optimized away if it is embedded in the QTransform::map(QPolygonF) overload. nx and ny are always 0 (as initialized by QPolygonF) after the macro (but only within the QTransform::map(QPolygonF) function. The bug happens only in a release build. Added debug messages of nx and ny created no output, adding qDebug() << t, which made the macro work. It seems that a complex combination of macro and switch statement can tigger the bug in gcc. So rewriting the macro as a function works around the bug.
