Re: [ALACPP] memory leak

[Ray Tayek <rtayek@xxxxxxxxxxx>]

the simple example below works. so i must be going south somewhere.



#ifndef LEAK_H_
#define LEAK_H_
#include <iostream>
#include <map>
using namespace std;
enum Direction {n,s,e,w};
class MapSite {};
class Leak
{
public:
Leak();
virtual ~Leak();
MapSite *get(Direction direction) const {
map<Direction,MapSite *>::const_iterator i=m.find(direction);
return i!=m.end()?i->second:NULL;
}
MapSite *insert(Direction direction,MapSite *mapSite) {
MapSite *rc=NULL;
pair<map<Direction,MapSite *>::iterator,bool> 
p=m.insert(map<Direction,MapSite *>::value_type(direction,mapSite));
if(!p.second)
{ rc=p.first->second; p.first->second=mapSite; }
return rc;
}
map<Direction,MapSite *> m;
};
int main() {
   new char[100],new char[101],new char[102],new char[103]; // force an error
Leak *l=new Leak();
l->insert(n,new MapSite());
l->insert(s,new MapSite());
for(Direction d=n;d<=w;d=(Direction)(d+1))
if(l->get(d))
delete l->get(d);
delete l;
return 0;
}
#endif /*LEAK_H_*/
