One thing I forgot to do is check that my minimization is exhaustive. After deleting all the pub static from the original crate it still ICEs, so there must be another way that it is triggering this too.

[apiraino]

Could this issue be related/duplicate of #93476 (and therefore fixed by #92533)?

Also, perhaps replace the team label with T-rustdoc?

I assume you meant #93539? That was included in last night's nightly which I tested with (we have a collection of failing crates in docs.rs that I am rebuilding as each fix for the fallout from #88679 lands).

[petrochenkov]

Fixed in #93766.
