Building cargo on Windows (-msvc toolchain) causes an ICE:
PS D:\code\cargo> cargo +nightly build
Compiling cargo v0.58.0 (D:\code\cargo)
thread 'rustc' panicked at 'assertion failed: !value.has_escaping_bound_vars()', /rustc/1f12ac87296ac61ec002e0243e7ad5a50364da35\compiler\rustc_middle\src\ty\sty.rs:974:9
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 1.58.0-nightly (1f12ac872 2021-10-17) running on x86_64-pc-windows-msvc
note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type lib
note: some of the compiler flags provided by cargo are hidden
