Just IMHO, it is not desirable to rely on runtime stack checking in an 
embedded application. What is the program supposed to do when a stack 
overrun is detected? Hand the user a box of candy? Explode?

It is preferable to analyze stack requirements beforehand, and monitor 
them during worst-case usage testing, if possible. Sometimes I add code 
to my watchdog-kicking code that checks for pre-RTL-init signature at 
the bottom of stack; if it's not there, I write a stack overflow 
diagnostic to the product log and stop kicking the dog to force a reset.
