ICE with -Zself-profile-events

[syntacticsugarglider]

Rustc encounters an internal compiler error when run with RUSTFLAGS="-Zself-profile=$(pwd)/profiles -Zself-profile-events=default,args" cargo +nightly build on this project. I've cloned all the git dependencies into that repo to maintain specific revs for reproducibility. The issue occurs on the latest nightly, version info is included below along with the specific error output.

It seems to be happening here in measureme so I'm not sure if here or on the measureme repo is the right place to report this but since it's causing an ICE I assumed it might be prudent to put it here.

This is blocking my ability to report a more pressing I-compilemem issue on the stable channel that causes some fairly trivial code to be OOM-killed on a system with 32GiB of memory, fwiw

[wesleywiser]

This was fixed by #77398.
