--- Comment #18 from Jeffrey A. Law <law at gcc dot gnu.org> --- Ah, a dockerfile for reproduction. Love it. I can fire that up here on one of my x86 systems as well. The BPI (native) is already building, but it's far from a performant system. I think the biggest question in my mind right now is whether or not we should be seeing those values inside that expander, so I'd like to throw it under a debugger and kind of walk through what's going on.
