magick++ --medianFilter

[mlin@pelmorex.com]

hi,

any suggestion on the following issue? Thanks
I used Magick++ and medianFilter as follows:
#include <Magick++.h>
image.read(srcimage);
image.medianFilter(3.0);
image.sample("500x500");
image.write(output);

but the valgrind complains the following error:
==25070== Thread 8:
==25070== Use of uninitialised value of size 8
==25070== at 0x3CDD0C7A15: (within /usr/lib64/libMagickCore.so.3.0.0)

Your code snippet worked for us with ImageMagick-6.6.4-9, the current release. For your release, try changing sample() to resize(). If that fails, you may have a buggy libgomp. Rebuild ImageMagick without OpenMP, add --disable-openmp to your configure script command line and then rebuild and reinstall ImageMagick.

Thanks.
I found the reason. It was because the call of image.medianFilter should not before sample
