Problem Title:
M1.3/M1.4 MAP - Map crashes due to an illegal pad configuration.
Problem Description:
The following circuit configuration will cause map to crash:
IPAD -> OBUF -> OPAD
|-> IFD
The circuit has an IPAD that feeds an OBUF directly as well as an
IFD. There should be an IBUF between the IPAD and an OBUF.
