Focus first on uses of unsafe-vector-ref and unsafe-vector-set!. (Not the fx 
and fl variants, just the plain ones).  I wound up removing these from the FFT 
code in order to get it to work.  

Check out bug PR 11264. 

Also, very late flash of insight: my response (getting rid of unsafe-vector-ref 
and unsafe-vector-set!) might explain my performance issues with the FFT
