CCSv5.3 MSP430 Debugger load/run problem

Other Parts Discussed in Thread: MSP430F5308

I am running CCSv5.3 and attempting to debug an MSP430F5308 on a custom board. The program loads, runs, and debugs properly if my un-intitialized variable arrays stay below ~1000 bytes. However, when I attempt to load the program with variable arrays larger than ~1k bytes, the program loads and runs but does not make it to main. It appears to be looping around

 __TI_decompress_none

or

__TI_zero_init

or

UCS_initFLLSettle

I am confuse as to why un-initialized variables (RAM) would affect code running in flash. Can anyone suggest a way to debug this issue?
