AO bug in 1.7.1

I think there is a problem with AO or GI in general 1.7.1.
I tried different settings for exposure, HDR, highlights, shadows and so on and the problem persists. I also checked various drivers for my graphics card.
For comparison, the shot was taken in versions 1.7 and 1.7.1. no post-production.
Contact shadows are missing in the newer version.
