How do I start the MPC5675K in Lockstep Mode?

Is there something special I need to do in order to run the MPC5675K EVB in lockstep mode?  I'm trying to run the example code that comes with Codewarrior (both MCU 10.5 and the Special Ed that comes with the board) for the MPC5675K in both Decoupled (DPM) and Lockstep (LSM) modes.  These projects are created with the project wizards with BookE and the SPFP options as well.  The code basically goes through the start up code, then drops into an infinite for loop.  In the DPM version the code works as expected, including initializing the P1 core.  But in LSM, I'm immediately through into the following exception vector:

 

ivor_branch_table_p0.c:

     .align SIXTEEN_BYTES

     IVOR1trap:  b IVOR1trap  /* Machine check / (NMI) interrupt handler */

 

I've not made any modifications to either code base on either edition of CodeWarrior.  Why doesn't the example code work?
