Created Unassigned: MagickImage.Resize(new MagickGeometry([int])); crashes/hangs [1408]

I've been using v7.0.0.0101 where Resize worked quite good. Now with current verisons (tried the last 3) it hangs/crashes and I'm getting no response or whatever. Instead the monitor get's dark and the memory increases. "AdpativeResize" still works fine but I need to Resize.
Thanx in advance!
