There is a function call in this loop as well.

Scalar evolution analysis fails here with:
failed: evolution of base is not affine.

  D.2768_8 = i_361 * stride_7(D);
  D.2769_9 = (long unsigned int) D.2768_8;
  D.2770_11 = src_10(D) + D.2769_9;
  D.2771_12 = *D.2770_11;

stride is function parameter.
