Out of bounds index in psy.c
V1.0.1..1.3.3 In function _vp_psy_init halfoc is limited to P_BANDS - 1 but later used +0 and +1
My guess is it should be P_BANDS - 2
Picked up when I recently translated the example enc/dec subset of ogg and vorbis to Google's Go as a "learn 2 things at once" exercise.
