error: the compiler unexpectedly panicked. this is a bug.

@matthiaskrgr, I've seen this on a few ICE reports, but I'd recommend putting the first ICE in the title instead of any other subsequent ICE messages, since this:

thread 'rustc' panicked at 'index out of bounds: the len is 1 but the index is 1', compiler/rustc_lint/src/internal.rs:481:82

really is the root cause of this issue, and the second one (mentioning BorrowMutError) is just a side-effect of panicking during certain queries 😸

@matthiaskrgr matthiaskrgr changed the title ICE: already borrowed: BorrowMutError ICE: 'index out of bounds: the len is 1 but the index is 1', compiler/rustc_lint/src/internal.rs:481:82 May 6, 2023
