I am bisecting the Julia repo for a bug, reproduced by a rather complex package that uses StaticArrays.jl. Around dbe19e49d9 (approximate, since I have been trying `git bisect skip` to get rid of this error, in vain) in the Julia repository, I am getting error messages like

The version I am using is `[90137ffa] StaticArrays v1.9.13` which works before and after (ie at `git bisect good` and `git bisect bad`). Again, I am bisecting Julia, not this package, but this is the one I cannot load to test a particular commit.

</div>

How to reproduce:

1. check out the Julia repository at eg `fea26ddecb8a6c404f0c501228bf17c9b384d686` and compile, start `julia`,
2. then

```julia
pkg> activate --temp
pkg> add StaticArrays@1.9.13

```

gives the above error message.

I’m also hitting this, but my bisect gives me [a version bump commit](https://github.com/JuliaLang/julia/commit/7053e4c26422ca821551a2b76ad08c16d81f999e) as the first where StaticArrays fails to precompile. The missing symbol in question was added (and backported to 1.12) [about a week ago](https://github.com/JuliaLang/julia/pull/57828)

</div>

OK, I think this is due to StaticArrays depending on PrecompileTools version 1.x.x, where version 1.3.0 declares compatibility with julia 1.12-nightly and looks for the new julia symbol. Not every commit with version 1.12-nightly contains the symbol, so PrecompileTools fails using julia between the two commits in my previous reply.

</div>

I added the following to my bisect script to resolve this

```julia
Pkg.add("PrecompileTools", io=devnull)
Pkg.add("Preferences", io=devnull)

using PrecompileTools, Preferences
set_preferences!(PrecompileTools, "precompile_workloads" => false; force=true)

```

The error is due to PrecompileTools not being supported until [Fix package precompilation (PrecompileTools) (#57828) · JuliaLang/julia@c89b1ff · GitHub](https://github.com/JuliaLang/julia/commit/c89b1ff7a1206e60e44a2e949041c33c4e853b16) on 1.12.

Thank you very much! With this I was able to complete the bisection.
