> M-x next-error
> compilation-next-error-function: Wrong type argument: arrayp, nil

Thanks, I just installed the patch below which should fix it.

> M-x compile
> run-hooks: Wrong type argument: number-or-marker-p, nil

I believe I've fixed this one yesterday or so.

> Can the "compilation--flush-parse: 1 16056" messages be turned off?
