Panic at "cannot update precise" in rust-lang/rust

Problem

When running cargo update -p icu_provider --precise 1.2.0 inside my rust-lang rust branch, I get

This seems to have regressed in rust-lang/rust#117302 via #12749. cc @Eh2406

Sorry. I will look into this!

Rustc is a big project with many moving pieces, and not when I contribute to regularly. I could use some help reproducing this issue. I checked out the commit @Nilstrieb link to but I cannot get anything to run. Stable complains about the use of public dependencies, nightly complaints about

error: failed to get `std_detect` as a dependency of package `std v0.0.0 (/local/home/jfinkelm/Cargo/rust/library/std)`

Caused by:
  failed to load source for dependency `std_detect`

Caused by:
  Unable to update /local/home/jfinkelm/Cargo/rust/library/stdarch/crates/std_detect

Caused by:
  failed to read `/local/home/jfinkelm/Cargo/rust/library/stdarch/crates/std_detect/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

with similar errors for locally compiled cargoes both before and after my PR.
Can someone give instructions to reproduce the problem, or create a self-contained example?

you might want to run something like

git submodule init
git submodule update library/stdarch

(sorry I am always forgetting the actual git command that works…)

Thank you, that helped! Now I am getting:

perhaps a crate was updated and forgotten to be re-vendored?
