A guard fault means you overran the end of the stack space.
I believe Apollo puts a write protected page of memory at
the end of the stack space to "guard" against programs
using more stack space than is available, thus causing
a memory page fault when you try to call a recursive routine
one time too many. You can increase the default stack size
with a switch to the binder (at least on SR10.2).
