It depends on the shell I guess because most machines run well.

That's a strange workaround. I don't understand why it works.
I am submitting a simpler fix adding " || true"

> -local_miss_maps=$(grep -L 'local: \*;' $@)
> +find_local_miss_maps ()
> +{
> +    local local_miss_maps=$(grep -L 'local: \*;' $@)

> +local_miss_maps=$(find_local_miss_maps $@)

Thanks for raising the issue and proposing a solution.
