Reproducible triggering of double precompilation

[baggepinnen]

From discussion on slack @IanButterworth
This is the terminal output after I trigger the sequence of actions that lead to double precompilation of the package PRONTO.jl. The steps are

1. Delete the folder .julia/compiled/v1.9/PRONTO and then run the commands below in a new julia session

pkg> activate --temp
pkg> add git@github.com:narijauskas/PRONTO.jl.git
julia> using PRONTO

---

Output:
double_precompilation.txt

The same procedure but starting julia with --startup-file=no
double_precompilation_no_startupfile.txt

It looks like you have a user startup file which loads StaticArraysCore which conflicts with your later attempt to activate a temporary environment for PRONTO. This is expected behavior of Julia in this case, as it is just following the commands from the user.

Slack discussion came to think that #44329 (comment) could help explain what's going on in this case
