Well, but it is not esy to do this in C. But it should be simple to add a 
small assembly routine just for the watchdog interrupt (using some examples).
I do not know IAR Workbench, I am using Crossworks. In similar cases I put a 
breakpoint at the reset vector and then examine the "execution trace" and the 
"call stack" windows. Execution trace is a feature of the MSP430-EEM, maybe 
IAR also implemented this.
