load_all fails on Windows

[swyant]

Given a YAML file like:

---
creator: LAMMPS
timestep: 0
...
---
creator: LAMMPS
timestep: 1
...

the following code:

julia> import YAML
julia> for fs in YAML.load_all(open("test.yaml"))
           @show fs
       end

results in

fs = Dict{Any, Any}("creator" => "LAMMPS", "timestep" => 0)
ERROR: AssertionError: typeof(forward!(composer.input)) == DocumentStartEvent

This issue only happens on Windows (specifically Windows 11), but works fine on Mac and Linux.

Thanks for any help!

This seems not solved yet.

From #214. This is really not OS specific but about \r\n:
