make check fails

[hmaarrfk]

Hi,

It seems that sines-test is failing on my computer

Example output from harminv

$ ./sines 0.1+0.01i 0.08+0.001i | ./harminv 0.05-0.15
frequency, decay constant, Q, amplitude, phase, error

(yes no frequencies were found)

It seems to work if we change the range in which we look for frequencies

./sines 0.1+0.01i 0.08+0.001i | ./harminv 0.05-0.16
frequency, decay constant, Q, amplitude, phase, error
0.08, 1.000000e-03, 251.327, 2, 3.14159, 8.834857e-16
0.1, 1.000000e-02, 31.4159, 1, 4.78299e-14, 1.692517e-15

both frequencies correctly found!!!

Any clue as to why this might happen?

Some kind of roundoff-error difference? It works for me with gcc on x86_64. What OS/machine/compiler are you using?

Fedora 22 x86_64

Strange.
