David, ix86 reports "nan" or "NaN" in the 0.40 stats line:

Linux glibc 2.2.x:

         0.30    0  0.000000  0.000000  
         0.40    0  0.000000  nan  
         0.50    0  0.000000  0.000000  

FreeBSD libc 4, Solaris 8 64-bit:

         0.30    0  0.000000  0.000000  
         0.40    0  0.000000  NaN  
         0.50    0  0.000000  0.000000  

Looks like Alphas generate an exception for that case where Sparcs and
AMDs don't. We need to fix some floating-point code.

Now watch this proof^Wtest program:

main() {
    volatile double a, b;
    a = 0.0;
    b = a/a;
    printf("%g %g\n", a, b);
    exit(0);
}

I have no idea yet what happens there.
