------- Comment #2 from bero at arklinux dot org 2007-12-26 23:32 ------- A Qt strict-aliasing bug potentially affecting this has shown up; it's possible that the problem isn't with gcc after all, but only shows up with the current versions. Running more tests with a fixed Qt version. (At a first quick look, I don't see how 130324->130330 could un-hide a strict-aliasing bug though, especially because the strict-aliasing bug is supposed to occur with 4.2.1 as well)
