Application Security Testing: An Integral Part of DevOps

I get a runtime error when I use the array delete operator

This is legal (safe) and works with the compiler environment I am using:
 CMyObject *ptr = NULL;
  delete ptr;
However, I get a run-time error (assert) when I use the array delete operator:
long *array = NULL;
  delete [] array;
Is the environment right or is it legal C++ to use array delete on a NULL pointer?

It is perfectly legal and safe to use delete or delete [] on null pointers. When called with a zero argument the operation has no effect.
