>Description:
#include <iostream>
#include <string>
#include <vector>

using namespace std;

class A {
public:
  A(string s) { sptr = new string; }
  ~A(void) { cerr << "delete " << sptr << "\n"; delete sptr; cerr << "delete done\n"; }
private:
  string* sptr;
};

int main()
{
  vector<A> avec;
  A a("a");
  avec.push_back(a);
  avec.push_back(a);

  cerr << "main done\n";
}
>How-To-Repeat:
Compile with g++ -Wall file -o test (no warnings are output)
Then just run it, it will segfault trying to delete the pointer A::sptr

Is this really a bug?
>Fix:
Unfortunately, I have no idea :-(
