using this code I can do only 32768 inserts, am I doing something wrong or can this template class only handle that few records ?

I hope this code looks better:

#include < stdlib >
#include < string >
#include < map >
#include < time >
using namespace std;

typedef map < long, long > mm;
typedef mm::value_type vt;
int main() {
    mm s;
    printf("%d\n",s.size());
    clock_t c1,c2;
    c1 = clock();
    for ( long i = 0; i < 100000;i++) {
        double val = rand() * 100000.0;
        s.insert(vt(val,9));
    }
    printf("%d\n",s.size());
    c2 = clock();
    printf("%d %d\n",c1,c2);
}
