Compiler Unexpected Panic: index out of bounds

[tsunrise]

Code

I'm not sure how to produce an minimal example here... but I tried to compile ark-bcs crate here: https://github.com/arkworks-rs/bcs/tree/7c8539b3bd84768abc920897ac6aacf178403f03

[M1ngXU]

just had the same problem with my own crate, also using nightly and having issues with a 'type' and a index out of bounds

Edit: same issue with stable version

Edit2: Fixing all clippy issues solved the problem
