Any idea why I had to fix a warning in a doctest to make
./x.py --stage 0 test src/libcore --test-args mem pass locally, even though CI seems to be fine with it?
I'm not sure we deny warnings, but it might also be that the beta compiler warns and master doesn't
well it calls out a
deny(warnings) in the error
but anyway this is https://github.com/rust-lang/rust/pull/61199
