If you're infinitely looping you're bound to access some restricted memory sooner or later.

Not if you're continuously re-examining the same memory!

Code Select Expand

while(true);

I doubt the above presents much threat of accessing dangerous memory.

That's true but how often is it that you do an infinite loop withought having any code in the middle? You're going to currupt the stack sooner or later.

That's still a terrible generalization...

Yea I guess, I assumed he knew what I meant. :P

Take a look at all the programs in this folder -- they're programs for my microcontroller.  Notice what they all have in common?  They all take place in an infinite loop.  And none of them corrupt the memory. 

Generally, they're a finite-state-machine, waiting for events, but there's no way to sleep on that uC, since my code is the only code running (no library, no kernel, etc).

Cool.

No stack corruption.

Ugh screw you guys :/

Okay, first of all, stack overflows != stack corruption.  Second of all, infinite looping != infinite recursion.

Infinite looping:

Code Select Expand


while (true) ;

Infinite recursion:

Code Select Expand


void doStuff(int a)
{
doStuff(++a);
}

Jackass.

Infinite recursion, a special case of an infinite loop, is an infinite loop caused by recursion.

And Rolle's Theorem is a special case of the Mean Value Theorem.  That doesn't make them the same thing.  Just because two things are related doesn't mean they're completely synonymous.

And? They're still related so I can call infinite recursion and infinite loop if I damn well feel like it and I will still be right.

Which makes me right.
