[WM]: fftw library and Stirmark

[Sergio Bravo Solorio <sbravo@lsc.fie.umich.mx>]

Hi watermarkers,

I am using Visual C++ v.6 to implement my watermarking scheme, and I use the fftw library (fftw3.h) to compute the FFT in the
embedding and extracting stages. The .exe program works very well, but I programed a dll in order to test my watermarking algorithm
with Stirmark. The functions (excluding the main function, of course) used in the dll are the same that were used in the .exe
program. However, Stirmark aborts the tests and an "unknown" assertion is reported exactly when the
fftw_execute(p) function is called by the extracting function. Do any of you have dealt with this problem? How did you solve it?

Best wishes!
