While testing my app, I found a bit of a problem with this function.
I've narrowed down the problem to its most simple form. Only seems to
happen with vDSP_destroy_fftsetupD, not vDSP_destroy_fftsetup.
Thought I'd also post this to coreaudio as fft is often used in audio
processing.
Any work around, short of leaking memory or reverse engineer the
structure and free it myself ?
Thanks,
Antoine
