Help : Is this a namespace collision ??

[Christian POKAM]

 Why is the Compilation of NewHandler.cpp complaining about  
     the ambigous use of "count" ??
 Thank you

using namespace std;

int count = 0;

void out_of_memory() {
  cerr << "memory exhausted after " << count
    << " allocations!" << endl;
  exit(1);
}

int main() {
  set_new_handler(out_of_memory);
  while(1) {
    count++;
    new int[1000]; // Exhausts memory
  }
} //


gcc version 3.2.1 ; linux kernel 2.4.19 ; glibc 2.3.1
gcc output:
