Yes, I do from time to time. The compilation issues changes over time. Currently it has problems with overriden methods of RTTI classes (TPersistent):

graphics.pp(189,15) Warning: An inherited method is hidden by "TFont.Assign(const tagLOGFONTA)"
graphics.pp(188,15) Error: There is no method in an ancestor class to be overridden: "TFont.Assign(TPersistent)"

Both errors make no sense to me.
