------- Comment #72 from jakub at gcc dot gnu dot org 2010-04-29 07:33 ------- There is no agreement on this being actually a bug, -mpreferred-stack-boundary is actually an ABI changing option and if you use it you are supposed to deal with the things it is causing (such as using -mstackrealign when calling code between the different ABIs).
