Hi,

I am trying to call an FFT library function from assembly code. I am working with ADSP 21396
processor (SHARC). I picked _cfftn_nonSIMD. I've tried using the SIMD version but it doesn't
work. Anyway, I don't have to use it since the FFT calculation is not under tight timing
constraints.  
The problem with the nonSIMD version is that it doesn't give correct results for 4096 points.
_cfft128_nonSIMD, _cfft256_nonSIMD, _cfft512_nonSIMD, _cfft1024_nonSIMD and _cfft2048_nonSIMD
all work, but _cfft4096_nonSIMD doesn't. It returns me garbage mostly -1.NAN. The size of input
and output arrays should not be a problem, I've checked that. It has to be something related to
the stack and memory and general, but I don't know what it could be. Anyone had a similar
problem?

Cheers,
Ivan
