On a lot of systems load from address zero doesn't segfault, I'm fine with the cpu loading it. I'm disappointed that the new compiler removed the check someone wrote a dozen years ago to prevent the cpu from overwriting something important though.
That case wasn't one of the cases where null pointers are valid memory, judging from the commit message. (There was a case where gcc had a bug where it didn't disable that check properly, but this doesn't appear to be that case.)
