<pre>This code
#include <stdio.h>
#define DEN 3.645199531882474602528e-4951L
int main(void){
static float f = DEN*DEN;
static double d = DEN*DEN;
static long double ld = DEN*DEN;
printf("DEN=%Lg, f=%g, d=%g, ld=%Lg\n", DEN, f, d, ld);
return 0;
}
prints 'inf' instead of the expected '0.0' for f, d, and ld.</pre>
