Segfault on showerror in v1.0 - latest

[fonsp]

I have tried to slim this down as much as possible, this is the best I could do:

runtests.jl

using Test

"something"
function jl_is_runnable(path)
    🏡 = Core.eval(Main, :(module asdf end))
    try
        Core.eval(🏡, :(include($path)))
    catch ex
        println.(enumerate(readlines(path; keep=true)))

        showerror(stderr, ex, stacktrace(catch_backtrace()))
    end
end

@test jl_is_runnable("./worse.jl")

worse.jl

@assert z == 10

The result is a segfault, on Linux, macOS and Windows, v1.0 until v1.5.

(Deleting any line from runtests.jl fixes the problem, hence the silly MWE.)

Running similar code gave me two different error messages: one, two. Hope these are helpful!

I made a repository containing just this MWE, with CI testing that segfaults on windows, macOS and linux:
