One of the fundamental point of using C++ ; is that the pointer
returned can not be null due to memory constraint and it will throw an
exception before this happen.
The only exception to this rule was VC6 that didn't conform to it and
would return 0.

There should be no need to test the returned value ; std::bad_alloc
will be thrown before.

It is usually a good practice to set the pointer to null prior after
calling delete, so you would test for null before the allocation is
performed; not after.

So this rule out the out of memory issue.
