I could remove the "build" dir and still reproduce, I don't think this is related to incremental compilation.

@matthiaskrgr But did you set RUSTC_WRAPPER=sccache? Removing the sccache dir may help.

Yes, I use sccache. I'll give it a try, thanks.

I thought using sccache while bootstrapping was opt-in, or was that some other project?

I don't know. I guess there is a bug in incremental compilation so the cached artifacts
aren't correctly rebuilted after the source code changed (or a bug in sccache itself).
