Sorry for the plotters dependency. I was unable to factor it out. The error disapperas if I remove any of the days.len(), days.iter() or chart.draw_series() calls.

cargo bisect-rustc --regress=ice -- build 

Also, maybe similar to #101020 but that one requires nightly, this does not (even though it doesn't fail on stable).

[compiler-errors]

hehe I'll fix this if not fixed by the same fix as #101020, probably is though

[compiler-errors]

I'll test this in a few days when #101020 is on nightly

[compiler-errors]

This no longer ICEs as far as I can tell.
