Lidi se nikdy nepouci... 

[man gcc]
       -ffast-math
              This option allows GCC to violate some ANSI or IEEE rules/speci-
              fications in the interest of optimizing code for speed.  For ex-
              ample,  it  allows  the compiler to assume arguments to the sqrt
              function are non-negative numbers.

              This option should never be turned on by any `-O'  option  since
              it  can  result in incorrect output for programs which depend on
              an exact implementation of IEEE or ANSI rules/specifications for
              math functions.
