Yes it does albeit slower. The code also compiles well if I omit the -ffast-math in the buggy routines (only 3 of them in 581) and use them in all the rest. > 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. Ok, point taken. A speedup is always welcome though. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27069
