Description
I tried this code: https://github.com/diesel-rs/diesel (diesel-rs/diesel@12429cb)
with the flowing command:
RUSTFLAGS="-Znext-solver" cargo +nightly check -p diesel
I expected to see this happen: Code compiles without error (as without the -Znext-solver flag)
Instead, this happened: Compilation produces error
Long error message
