No. The problem with cracking was with the old Pista/Stada design prior to the C-Record. The preventive modifications are, I think, well documented. Cranks can crack, especially around the pedal eye but there is little empirical experience to suggest that modern Campa Pista faults are more frequent than those found with the contemporary Sugino 75 or Dura Ace 7600 square taper cranks... The main problem is typically a product of fretting corrosion. Use of a suitable assembly paste as commonly used in the automotive industry, however, can help to reduce tribocorrosion. Klüberpaste 46 MR 401 is a favorite. I've lately been also using some Wera Ceramic Paste in screw applications--- such as pedal/crank interfaces.
