I must be missing something basic....

I am evaluating 6.3, and I can’t get the proverbial 3 liner to compile:

#include <list>
#include <string>
#include <iostream>
using namespace std;

int main(void)
{
  list<string *> foo;
  string         bar("BAR");

  foo.push_back(new string(bar));

  cout << *(*(foo.begin())) << endl;
}

compiled with:

QCC -V3.3.1,gcc_ntox86 -o list list.cc

Errors:

What am I doing wrong ?

Needless to say the preceding compiles (and even works) on 6.2.1 with the following compiler invocation:

QCC -olist list.cc
