[11:00:43] <jamrial> michaelni: what do you think of 8f5de34c? does it apply to us?
[11:01:50] <jamrial> our code started to deviate with your commit bca59d77, followed by the merge commit aa40df48
[11:33:51] <michaelni> jamrial, the fade commits are from 2013, but i think our fixes where complete and the problematic slice_h FFALIGN is also removed
