Steve,
Thanks for the reply.
You're right, I was asking "how can I get around this gdb error".
Since then I 've managed to solve my immediate problem--it was a subtle but improper data setup prior to calling the vDSP function vDSP_fft_zipD (subtle, at least to me). That fixed and the gdb error is no more.
Still, I would like to know a bit more about the "Error from Debugger:Previous frame inner to this frame (gdb could not unwind past this frame)" error--conditions that cause it and strategies to counter it. Are you aware of any references?
Again, thanks. Don
