Okay, how do i put this gently: If you want to argue about strict aliasing and enabling it by default, please don't do it in a bug report. We use bug reports to track the status of very specific bugs. Even if we were to perform the behavior you request (and I highly doubt we will), it would be a separate enhancement request, and should be filed as such (and probably discussed on the gcc mailing list prior to filing a report). We have our reasons to enable strict aliasing by default. People have their reasons they don't like it. Acting as if one viewpoint is simply invalid because you don't like it isn't going to help. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28778
