Occurs when trying to add DifferentialEquations either to the global environment or any local environment. During the precompilation step it ends up hanging on BoundaryValueDiffEq… I’ve tried a few different times for over 20 minutes each, including one overnight (~8 hours).

This is in Julia 1.10.4 on Arch. Most recent attempt was in the global environment. Here’s the result of `]st` beforehand:

```julia

⌃ [0656b61e] GLFW_jll v3.3.9+0 ⚲
  [9a3f8284] Random

```

After `]add DifferentialEquations`, and interrupting to maybe show where it’s hanging (note the 1/3 is the result of several dependencies already being compiled from previous attempts):

Any ideas? Earlier version I should fall back to?

Yes, using the `curl -fsSL https://install.julialang.org | sh` install method.

Interesting, that was supposed to be fixed by Julia v1.10.4. I’ll see if anyone else can reproduce from the compiler team.
