This is for 4.3.5. That doesn't suggest anything to me and actually it's rather surprising. -O2 is much more aggressive than -O1 when it comes to breaking code which superficially looks like it should work. When code breaks with -O1 it usually means that the code is obviously broken. Or, of course, there could be a compiler bug. Sorry I can't of much help here. What you are asking seems to be a reasonable question but unfortunately the gcc release process doesn't work in a way that makes it possible to answer it. Ian
