+Subject: [PATCH] Fix the half-octave bounds check in _vp_psy_init
+
+The existing code ensured that halfoc would not exceed P_BANDS-1,
+ but the interpolation used index P_BANDS (albeit with a weight
+ of 0) when this bound was actually hit.
+Add an extra clamp on the integer index to avoid this.
+Thanks to Paul Adenot for the report.
+
+Fixes #2353
