Regression in nightly-2023-02-05 Regression in 886b2c3e005b153b3c8263f48193e0df7de0f5b3 https://github.com/rust-lang/rust/pull/107551 cc @fee1-dead
Fixed on the latest nightly, marking as E-needs-test @rustbot labels: +E-needs-test
I don't think this is actually fixed, just that the ICE cannot be triggered currently, but might resurface when the effects feature is fully implemented.
