Don't check a pointer before deleting it, just delete it.

// don't do this
if ( p ) delete p;

// just do this
delete p;

// ie: this doesn't crash or do anything bad
int* p = NULL;
delete p;

// but you probably need something like this
#define NUL_DEL( p ) { delete p; p = NULL; }

But seriously, this isn't the dark ages, you really want to be doing this.

std::shared_ptr<int> p;
p.reset(); // no need to set to NULL (or rather null_ptr)
