Could you post (or send me privately) the .pcb file? 


Here is a simplified file that only contains the problematic footprint.
Quite possibly this is just a problem with the footprint?  After all
this was hand-coded in M4...

I'd be more likely to suspect the footprint if "after all it was hand drawn instead of generated programattically"...

Ok, here's the deal. It is a bug in pcb. Square (or rectangular) pads are checked by growing one of them in X and Y on all 4 sides by the minimum space. This of course means that the corners grew by sqrt(2) more and thats why you got a failures. I'll try to cook up a patch tonight.

I took a quick look at that footprint and it is similar but not quite the same as the TQFN_40_6_EP in the ~geda library.
