Hello Peter,

meanwhile I have a quick fix:

On Wed, 18 Jan 2017, gedau AT igor2 DOT repo DOT hu wrote:

I went on and modified this one to reset NoHolesValid in case it exits 
because of the silk restriction (svn r6338).

It seems to fix the problem, restoring proper operation in the 
no-clearance-on-silk setup while it doesn't seem to break anything else. 
Maybe a similar quick-fix patch would be reasonable in mainline, 
independent on how this whole question is handled long term.

Regards,

Igor2
