Can not enable watchdog on custom board.

I'm using an MKL26Z128 and cannot seem to enable the COP (watchdog).  I can get it to work on the FRDM board that I have by commenting out the SIM_COPC = 0x00 line in the start() function.  If I comment out the same line of code for the custom board it has no effect, COP is always disabled.  I've searched the code for any reference to SIM_COPC and the line in start() is the only one I find.  I'm using IAR Embedded Workbench.  Is there some setting in the IAR tool that I may have missed that would cause this behavior.  It acts as if the SIM_COPC register is being written to, one time write after reset, but I can't seem to locate where that might be happening.
