So none else currently has any problems with WX GUI FFT functionality in 3.7 at  head of master? (c1f0b50d1d5a817c98130726997ba284ea980d95)
I'd be grateful if someone could try the attached test case flow graph and see if they can reproduce these (incorrect) results http://ianbuckley.net/fft3.7_test.png

I was expecting something very close to this output from 3.6: http://ianbuckley.net/fft3.6_test.png


My thoughts on this are that wxFFT is somehow inserting random phase-noise, or that somebody's putting in a **2 where an **1 belongs.
