--- Comment #3 from Eli Friedman <efriedma at quicinc.com> ---
Found a related miscompile, pushed
https://github.com/llvm/llvm-project/commit/bf0d0671a1062aec973c14522d6accf0c438b92e
.  That isn't relevant to either of the commands you're trying, though.

Code is expected to indicate explicitly to the compiler when an access might be
unaligned.  The usual recommended patch to the code is to memcpy from the
buffer to a local variable, or vice versa.
