Rust internal Compiler Error when building SMT2 crate using nightly

[Lukas-Dresel]

Code

Simply cargo build using the SMT2 crate as a dependency using rust nightly (1.57.0)

Meta

note: rustc 1.57.0-nightly (aa7aca3b9 2021-09-30) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 --crate-type lib

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

This looks similar to #89393, I can close this if this is a confirmed duplicate.

[Nadrieril]

Yep, definitely a duplicate
