What I mean is that I can use the feature of allocate to stop the system running.
For example, my machine has 62G memory.
Then I define an array allocatable in fortran. If i allocate the array for 62G, the allocate operation will failed. Only when I allocate 60G or less, it can be success.
And the allocate function doesn't allocate the memory for the array unless I initilize the array.
So I define two allocatable arrays, and allocate them both by 60G. The allocate operation succeed.Then I valued them one by one. My computer went down.
