One trick I use with my multitasking OS is to fill each stack with 0xaa
at startup. Then I go into a debugging session with the JTAGICE after
the program has run for a while and do a memory dump of the stack. It's
usually obvious how much of the stack has been used.

Of course, you can't use JTAGICE with the 8535, but you might be able to
do something similar in a simulator.
