Unhappy program to crash a system or corrupt memory


I had an interview yesterday and was asked to write a program to crash a system or corrupt it. I tried using arrays by defining a size and exceeding the bound. But he said, the data will be overwritten but the system will not crash.
Do you have any answers to crash the system?

just make fork() in recursion.

That will hog the system to a crawl.

And then system will crash surely.

@piyush gupta, can u gimme that TSR with complete procedure. Even I was asked the same que in an interview to write a code that can infect or crash the system but my clever answer was that " I cant think destructive". I was not selected there (What did ya expected? hehe... )

Make a program to intrude into registry and dismantle it. You are done.
