Clippy crashes with 'attempted to read from stolen value'

[atahanyorganci]

Clippy crashes when compiling proc_macro crate, query stack during the panic is the following. I also attached stderr with RUST_BACKTRACE=full, rebuilding after running cargo clean fixes the issue.
crash.log

#0 [unsafety_check_result] unsafety-checking `<impl at mal-derive/src/lib.rs:18:1: 44:2>::parse`
#1 [analysis] running analysis passes on this crate
