md5sum confirmed.

You mean the mountain-turns-into-logo thing? Looks fine here.
Could you do me a favour and add these lines

#undef printf
#define MV_TRC(X) printf("[%d,%d]",h->mv[(X)].x, h->mv[(X)].y);
    printf("pic %d MB %d,%d ",h->picture.poc,h->mbx,h->mby);
    MV_TRC(5); MV_TRC(6);
    MV_TRC(9); MV_TRC(10);
    MV_TRC(17); MV_TRC(18);
    MV_TRC(21); MV_TRC(22);
    printf("\n");

at line 711 right at the beginning of function inter_pred,
then run

./ffplay stream01.avs > mv_trace

until you see those artefacts, then somehow make mv_trace available
to me?
