calling new when heap is full

[codebusters]

Hi, I want to know what happens when we call new when the heap is full. Do we get a core dump or does the program just stops or what exactly?
Thanks

(1) throwing allocation
    Allocates size bytes of storage, suitably aligned to represent any object of that size, and returns a non-null pointer to the first byte of this block.
    On failure, it throws a bad_alloc exception.
(2) nothrow allocation
    Same as above (1), except that on failure it returns a null pointer instead of throwing an exception.

        C++98
        C++11

    If replaced, both the first and second versions shall return pointers with identical properties.
(3) placement
    Simply returns ptr (no storage is allocated).
    Notice though that, if the function is called by a new-expression, the proper initialization will be performed (for class objects, this includes calling its default constructor).
