Yes, it should report it. It is fixed in CVS. Thanks for the bug catching! > 2) I'm sorry, but (as usual), I can't find anything to answer my > question in the wiki.

Place and connect to those pins the noconnection symbol (misc/nc-*-1.sym). This will connect that pins to the net "NoConnection", which is not checked in the DRC. However, be aware that gnetlist and gsch2pcb will conect those non-connected pins together. We have to find a way to avoid this, but it is to be done yet. Regards, Carlos
