/* This is a debug tool used to detect bitstream error. On encoder side, it
 * pushes each bit and probability into a queue before the bit is written into
 * the Arithmetic coder. On decoder side, whenever a bit is read out from the
 * Arithmetic coder, it pops out the reference bit and probability from the
 * queue as well. If the two results do not match, this debug tool will report
 * an error.  This tool can be used to pin down the bitstream error precisely.
 * By combining gdb's backtrace method, we can detect which module causes the
 * bitstream error. */
