Shouldn't be hard. Use the 8k stack, and have the system mark the second
page as "not present"
If it ever gets used you get a page fault. The page fault handler then
have to mark the page
present before returning, as well as queue up some spam (the call chain
perhaps) for the log.
A less intrusive way is to use 8k stacks as-is, but put a signature in
the second page.
When the process quits, examine the second stack page to see if the
signature
got overwritten. This approach will only show that a problem exists, it
won't
pinpoint exactly what does it.
