commit 0ae66d565e6bead8604d312bc1a4e9dccf245c88
Author: Tim Terriberry <tterribe@xiph.org>

    Fix pp_sharp_mod calculation.

    This was broken when the dequant_tables indexing changed in commit
     r16102, but it only affected post-processing quality, so we never
     noticed.
    With gcc 4.8.0, this can now trigger a segfault during decoder
     initialization.
