ICE: range start index 2 out of range for slice of length 0', library/core/src/slice/index.rs:52:5

Code

Not reduced so far. Can reproduce by checking out the code from https://github.com/InstantDomain/instant-xml/tree/ice and running cargo test (running cargo check is not enough). See the last commit for triggering changes.

Error output

thread 'rustc' panicked at 'range start index 2 out of range for slice of length 0', library/core/src/slice/index.rs:52:5

error: internal compiler error: unexpected panic

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

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.63.0 (4b91a6ea7 2022-08-08) running on aarch64-apple-darwin

note: compiler flags: -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C incremental

note: some of the compiler flags provided by cargo are hidden
