Does your code work correctly if you omit -ffast-math? Have you audited your code to ensure all floating points operations meet the expectations of -ffast-math? I note that your computing an FFT and doing some complex arithmetic with numbers from the fft. I won't use -ffast-math in this situation. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27069
