Got an ICE while trying to make a crate that implements Julia-like broadcast functionality. Not the most minimal example:
https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=64799ae35f987dc509e11973c1f20153

backtrace 
thread 'rustc' panicked at 'Unknown variable: 0', compiler/rustc_ty_utils/src/instance.rs:46:17
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

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 1.55.0-nightly (955b9c0d4 2021-07-12) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C codegen-units=1 -C debuginfo=2 --crate-type bin

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

query stack during panic:
thread 'rustc' panicked at 'substs of instance DefId(0:4 ~ playground[d8fc]::TensorDimension::DIM) not normalized for codegen: [^1]', compiler/rustc_middle/src/ty/instance.rs:286:9
