You probably can try to run regression testing just with stage1 compiler to see if there is any regression exposed. If without any luck, then you probably have to isolate into one or several object files, since you have "objects" for "good" and "bad" stage1 compiler, you can be able to isolate some in between further. Once you get some isola= ted, you can probably get some hints it's a bug in LLVM source or gcc. It seems you are using gcc 13.2.1 as version field shows, you can also try = some previous versions like gcc 12 and gcc 11 to see if they work and it's regressed.=
