When I run cargo clippy on the RustPython project, Clippy panics while compiling RustPython in the NormalizeAfterErasingRegionsFolder:: normalize_generic_arg_after_erasing_regions of rustc. I'm on the M1 Max MacBook Pro running macOS Monterey 12.4.

Edit: the above method is being called from clippy_utils/src/ty.rs#L71

Here is the full backtrace 
    Checking rustpython-vm v0.1.2 (/Users/vsong/Downloads/RustPython/vm)
