Sorry for the late reply. I see what is going on already. The bits_to_bytes()
function is buggy for bool type. Bool is the only type has bits less than 8.
It truncates the bool byte size to 0. As a result, the array layout function
convert_index() always set the expr->init_offset to 0 for bool type:
"e->init_offset = from * bits_to_bytes(e->ctype->bit_size);"
