Unregistered user When this program is compiled and run with GCC, it complains of a corrupt heap:

#include <stdio.h>
#include <stdlib.h>

class foo
{
public:
int blah;
foo() {printf("foo at %d\n",(int) this);}
~foo() {printf("foo killed at %d\n",(int) this);}
};

void main()
{
poo *t;
t = new foo[10];
delete t;
}

Basically what I want to know is whether this is a bug in GCC, a limit of C++, or that I've done something wrong somewhere.

I got a seg fault from Linux. Platform independence!

You need to alter the delete so that you're deleting an array of foos, not an individual foo.

foo *t;
t = new foo();
delete t;

foo *t;
t = new foo[10];
delete [ ] t;

Unregistered user Ah, right. I think I tried delete t[], but not delete []t.
