Found one place where memset goes out of bounds but this problem caused
by different means.
It happens only on Sample.rmvb (http://samples.mplayerhq.hu/real/VC-RV40/)
and looks like it does so because of some additional unknown codec.
I must add this happens by passing icodec->pix_fmt=-1 to sws_getContext()
even before codec init.
