step_by + skip produce incorrect results #55985
Description
The following snippet demonstrates the problem:
println!("first"); for i in (0..640).step_by(128) { println!("{}", i) } println!("second"); for i in (0..640).step_by(128).skip(1) { println!("{}", i) } println!("third"); for i in (0..640).step_by(128).map(|i| i).skip(1) { println!("{}", i) }It prints:
first 0 128 256 384 512 second 128 129 257 385 513 third 128 256 384 512 I expect second iterator to produce the same result as for the third one.
