Crash in H.263 encoder

Hi,

I am seeing a crash in the H.263 encoder when using UMV and Advance Prediction.
The crash happens within ippVideoEncoderH263::ME_SAD_8x8 calling h263e_ME_HalfPel_SAD_8x8.
This happens only when compiling with optimisations. It is caused by using xPos and yPos with uninitialized values.

A workaround is to initialize the entries of xPos and yPos to 0

I am using IPP 6.1 update 5 with samples 6.1.5.068
