From what I can figure out, this problem seems to be in the ARP shell.
We use the standard, Commodore-defined methodology for determining the size
of the stack (See RKM vol 1), and ARP does not always follow the rules when
allocating stacks.  We were not aware of this problem until a few days ago.  
I recommend using another shell, or alternatively compiling with -v to suppress
stack-checking.

The stack-checking code works perfectly with CLI, Commodore's Shell and
WShell.  These are all the shells I have had experience with.
