`std` build fails with newest rust nightly

Question

`std` build fails with newest rust nightly

N3xed opened this issue 2 years ago · 3 comments

The latest working nightly was the previous one, so 2022-08-01. This also caused esp-idf-sys CI to fail (only the one run that's using current nightly, the other three use esp-rs/rust).
