fft2 benchmark sometimes fails (nofib)
I noticed that sometimes fft2
program in nofib benchmark suite returns values that are slightly different from expected (see error message at the end of this report). The most worrying for me is that it sometimes works properly and sometimes fails, as if the correctness of result depended on some random factor.
