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.
