Name ONE operating system that does this. Besides, if I were to write a

But that just invites trying to crash your program in such a way that
it's cleanup routine won't be run.
It invites the attempt but doesn't mean it will happen. An OS that
clears memory before it allocates can still have failure modes where
it doesn't do that right. Also lowering the CPU voltage or stopping
its clock or running a huge program with a high priority to force a
swap to disk followed by a power off. I can think of many ways to
try.
