Bagas, sorry for being blunt here, I know you mean well. But I feel the need to say the following in the open, as this otherwise falls back on me and regression tracking. Stating the above is not very helpful, as Dave for sure will know. Telling Phillip that he likely can skip that commit might have been something different. But I guess even for most users that are able to do a bisection it's obvious and maybe not worth pointing out. Ciao, Thorsten
