I had actually thought that there were earlier passes that added initialization. If that is true, then the real question is why did they fail to make this go away earlier. on the other hand, if there is nothing to resolve these earlier, then i guess we need to fix it up here. But again, i am surprised that this is the first time we have seen this problem. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42631
