@WG-prioritization/alerts issue #74258 has been requested for prioritization.
I'm not finding any similar issues that have happened when compiling regular (ie, not rustc) code.
I would not expect this to ever happen again TBH
this is me halfway through messing with x.py itself
Have you seen it since then?
Ok, it does seem very possible that changing rustbuild configuration like you mentioned could do weird things like this.
I'm inclined to just close if you haven't seen it since.
sounds good to me, if it happens to pop up again I can open a new issue
but I don't expect that to happen
Issue #74258's prioritization request has been removed.
