CW 8.8 Crashes. Please help ...

We are facing CW crashes everytime our application accesses the R1 register of the MPC 8360 in our application. This is a standalone application built to execute out of RAM. So we have not imported any source files into the CW debugger. All our debugging happens using PowerPC assembly language. The problem occurs during our Interrupt Service Routine (ISR) where we access the R1 (Stack Pointer) register. At this point CW invariably crashes with the following error:

CodeWarrior encountered an unhandled exception 0xc0000005 at address 0x02aec39d (The memory at address 0x00000000 could not be read).

Is it necessary that our application has to link with a small CW application which handles all exceptions or can my application run as an independent entity?
Please do help me out here,
