overflow evaluating the requirement `<I as ToOwned>::Owned normalizes-to _` with `-Znew-solver` and winnow

[weiznich]

I tried this code:

cargo +nightly create test_winnow
cd test_winnow
cargo +nightly add winnow@0.5.32
RUSTFLAGS="-Znext-solver" cargo +nightly check

I expected to see this happen: Code compiles without error as it does without -Znext-solver

Instead, this happened: Compilation fails
