Problem using Code Composer with MSP430FE4272 eval board

I am using Code Composer V4.2.  I am running the demo 2 software provided with the EVM430-FE4272 evaluation board. At the start of main(), after the watchdog timer is disabled, there is a call to init_fll(10, defSystemFreq, 32).  defSystemFreq is defined to be 1024*MCLK_FREQ, where MCLK_FREQ is 8. Executing the init_fll() function seems to cause problems single stepping with Code Composer. I can single step for a few lines of code and then I lose control and the debugger doesn't come back.  Also, there is a problem examining variables in the local or watch windows. The values displayed do not get updated. If I comment out the call to init_fll() then the debugger works fine. I can single step and variables displayed are updated. However, when commenting out the call to init_fll(), I then encounter a different problem in which the uart communication no longer works. Has anyone seen any of these problems?
