at least 16 bytes or a C99 variable-length array variable always has
alignment of at least 16 bytes."

Rui Ueyama dcd4579226 Handle a function returning bool, char or short 
x86-64 psABI says that only the least significant 8 bits are
significant if RAX has a return value of a function returning bool.
Likewise, it looks like only the least significant 1 or 2 bytes
are guaranteed to have a correct value for char and short return
values, respectively.
