Confirmed, it's an ABI change. Turns out the old behvior never actually matched GCC in the first place. This was just a bug where integer complex types got treated like FP complex types and split across GARs when they shouldn't have been. Since it's fixing something that was already broken, I'd rather get it in sooner than later so we don't keep emitting code that doesn't match GCC's ABI. Thanks!
