Ice: panicked at compiler/rustc_metadata/src/dependency_format.rs:352:24: index out of bounds: the len is 124 but the index is 128

With:
rust version 1.80.0-nightly (a330e4959 2024-06-04)

I don't have a reproducer yet but we haven't been able to build the Rust coreutils with nightly for a few days

error: the compiler unexpectedly panicked. this is a bug.

This should be a duplicate of #125934, so I hoped this issue would also be fixed by #125493 (in particular because this reproduces locally as a compiler/rustc_codegen_ssa/src/back/link.rs:2700 panic instead, like all the other ICEs fixed by the PR), but it looks like it actually won't.
