memory leak in DLD using FFTW3

hi octavers,

I have located a memory leak in a DLD function of mine which calls FFTW
version 3.0 

I have isolated the problem in the simple CC code attached to this

To make the oct file:
mkoctfile --verbose  -I/usr/local/include -L/usr/local/lib -lfftw3

Then, run the following line in octave2.1

x=zeros(1024,1);for icol=1:2000,dummy=fft_test(x);end;

while looking to the memory.

On my computer, the memory space used is increasing (available
free mem decreasing). The memory seems to be freed only when quitting
octave. Do you experience the same thing on your machine?
Somebody has a hint of what I done wrong?

I am running octave 2.1.35   (i386-pc-linux-gnu)
(as available in current debian stable 3.1).
