Replying to [comment:7 jamal]:
> Also, as you said ahthovaikied used two different compiler versions.
I had tested with a newer and an older gcc version than ahthovaikied (but
not the same) and could not reproduce a difference.
> On top of that one configured with --cpu=corei7 and the other --cpu
=core-avx-i, so even more chances for different float output.
I also tested the different configure options and saw no difference.
Or to say it differently: We both agree that AAC is not necessarily bit-
exact but I would still like to know how to reproduce this issue (while I
find it less interesting to know which commit broke library upwards-
compatibility).
