Sysimage precompilation error on Github CI / Docker image

[Olivier Labayle]

Hi,

I am trying to build an app with Comonicon but the sysimage creation fails when loading my Package in the Julia script generated by PackageCompiler. (This line:)

Base.require(Base.PkgId(Base.UUID("2573d147-4098-46ba-9db2-8608d210ccac"), "TargetedEstimation"))

This is apparently (see stacktrace below) because of the following Comonicon line: src/frontend/cast.jl#L529

$doc = @doc(COMMAND_ENTRY_DOC_STUB)

I can successfuly build the app on a local linux machine but it fails on both a Github CI runner (Ubuntu 22.04.3 LTS) and a Julia official docker container on the same github CI runner. This makes me think it must be due to some environment variable but can't really figure it out. I think I understood that bandwith is low and would be grateful for any help or hint for what is happening if any idea comes to mind.

The full stacktrace:
