I looks like the following lines (1456 to 1462 in TComSampleAdaptiveOffset.cpp) fell victim to some erroneous search/replace.

#if FULL_NBIT

m_uiSaoBitIncrease = g_uiBitDepth + (g_uiBitDepth-8) - min((Int)(g_uiBitDepth + (g_uiBitDepth-8)), 10);

#else

m_uiSaoBitIncrease = g_uiBitDepth + g_uiBitIncrement - min((Int)(g_uiBitDepth + g_uiBitIncrement), 10);

#endif

The problem appears fixed if they are changed to just:

m_uiSaoBitIncrease = g_uiBitDepth + g_uiBitIncrement - min((Int)(g_uiBitDepth + g_uiBitIncrement), 10);
