Thanks for your answer. However, the 2nd example I gave in the bug report
#include <stdlib.h>
#include <stdio.h>

main()
{
  double e = atof("0.2")*atof("5.0");
  if (e>1.0)
    printf("0.2 * 5.0 > 1.0 (ERROR)\n");
  else
    printf("0.2 * 5.0 <= 1.0 (OK)\n");
}
does "store the multiplication into a temporary variable" (quoting your words)
('e'), but it certainly does not "work as I am expecting" when compiled with -O1.
Could you please explain to me?
