Logic error "Result of operation is garbage or undefined" in crypto_aesctr_stream_cipherblock_use.
crypto_aesctr_stream_cipherblock_use
This is discussed in https://github.com/Tarsnap/libcperciva/issues/372.

Logic error "Assigned value is garbage or undefined" in _mm_loadu_si64 (called from cpusupport-X86-AESNI.c)
_mm_loadu_si64
cpusupport-X86-AESNI.c
This is discussed in https://github.com/Tarsnap/libcperciva/issues/423.
TL;DR: clang-scan doesn't like its own <emmintrin.h> header.
