commit b35c38c6e44b0df0fc2c5a3983ecd7547b964691
Author: Tomaž Vajngerl <tomaz.vajng...@collabora.com>

invalid array index when pCurrent pointer is incremented
If pCurrent is incremented (when the input double array is not
alligned) we can't use i as the array index anymore as it refers
correctly to elements in input double array only. Changing back
to pointer arithmetic.
