Yes, this is a bug. Without looking at the code, it looks like a sign reversal (perhaps due to an overflow) in the intensity-to-blue deltas. We'll write to this bug when this is fixed.
Out of curiosity -- did you find this with SSIMULACRA or was this the first image you tried?

I looked at 20 images and 3 or 4 of them had this problem. This was the one where it was most obvious.

The first attempt to reproduce this failed, this bug could be related to the undefined behavior found in other issues. If you could upload the related .pik file, we could find out if this problem is in the decoder or in encoder, and reduce the space for bug hunting.

Just a FYI, this problem happens on some compilers and not with others. We will provide a fix in a few days.
