In 4b4b680c I passed a buffer index number (starting from 0) instead of a proper Buffer id (which start from 1 for shared buffers) in two places. This wasn't noticed so far as one of those locations isn't compiled at all (PrintPinnedBufs) and the other one (InvalidBuffer) requires a unlikely, but possible, set of circumstances to trigger a symptom. To reduce the likelihood of such incidents a bit also convert existing open coded mappings from buffer descriptors to buffer ids with BufferDescriptorGetBuffer().
