[Bug c++/32984] New: add checking for array new & delete

["dcb314 at hotmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Given the following C++ code

class K
{
public:
        void f();
        void g();

private:
        int * a;
        double * b;
        float * c;
        unsigned int * d;
};

void K :: f()
{
        a = new int;
        b = new double [ 10];
        delete c;
        delete [] d;
}

void K :: g()
{
        delete [] a;    // error
        delete b;               // error
        c = new float [ 20];    // error
        d = new unsigned int;   // error
}

Recent snapshot g++ 4.3 20070803 can't find anything
wrong with the code.

Suggest enhance compiler to track use of plain new/delete
and array new/delete and warn where possible to detect 
an error.

Manual memory allocation and de-allocation is enough
of a pain in C++ without total silence from the compiler.
