Description

The memset call at line 419 goes partially outside the buffer area reserved for the PixDiff values.
This is caused by a wrong expression in line 418.

If you replace NR2*2 by NR2*LrBorder at the end of minLr[k] calculation there, the buffer access stays within its borders and the line becomes consistent with the other assignments to minLr[?] in the code.
