Anybody still has MSVC 2015 update 1? It seems that MSVC 2015U2 miscompiles stream_encoder_intrin_sse2.c, stream_encoder_intrin_ssse3.c (and probably stream_encoder_intrin_avx2.c, but currently I cannot test it 'cause I don't have avx2 CPU). I wonder what happened and what changed in the asm code that MSVC generates.
