Oops, i missed this issue. Tested with all pending PR's included.
0046 0047 0136 and 0162 seem to be related to greens matching and smoothing. I will check that again.

No idea now about 0176, i guess would be use of hypotf() instead of fast_hypot()

I would propose to leave these tests out from updating until fully understood and fixed.
