ippiPyramidLayerDown fails although it should not

Hi All,

ippiPyramidLayerDown consistently fails to compute the last pyramid level (Exit status -6 (ippStsSizeErr: Incorrect value for data size)). All one has to do is to feed it some non-default resolutions. Reproducer is attached, PyramidLayerDown.c. All I changed was the resoution, the rest of the code is identical with the original sample code.

The underlying reason seems to be an issue in IppiPyramidDownState. If I create a separate IppiPyramidDownState for each downsampling step from level i-1 to level i, then the error does not show. But IppiPyramidDownState should work for all pyramid levels, not just some.

Below you find the output of GetLibVersion for the IPP installation on my machine (Windows 8.1, 64 Bit).

Thanks,
Thomas
