+Subject: [PATCH] Fix big-endian bugs in CodingPathSync tests
+
+Change Serialize() to read uint16_t samples correctly. Although only the
+least significant byte of each sample is nonzero, we cannot assume the
+least significant byte of the c-th sample in `row` is row[c * 2]. That
+is correct only on little-endian systems.
