Now I'm confused. If the bug is not present in 3.3.3, then what is there to backport? Or are you saying that the bug is present, but that this particular testcase doesn't tweak the bug because of some other difference between Debian's gcc and ours? If this is the case, then this is yet another argument for my goal of getting the Debian and FSF gcc's to be as identical as possible, so that both will be as reliable as possible. If only one side does changes, then those changes get less testing (especially on less common platforms). > In fact, the patch for that bug hasn't been installed on the 3.3 branch > yet.
