Mark, many thx for your reply:

Well, that was 6 days ago and nothing further happened. Makes me wonder:
Who will look into this? And when? If not any time soon I guess we
sooner or later should consider revert this. Yes, the problem is "just"
a warning, but well, it's not "just" a warning for people using
panic_on_warn...
Paul, just to be sure: I assume reverting 2f189493ae32 fixes the problem?
Ciao, Thorsten
