    Otherwise, if src_bit_size > 0 and dst_bit_size == 0, we end up doing a

    negative value (in this case would be MAX_UINT32).
    
    Fixes CID#1468134 "Bad bit shift operation (BAD_SHIFT)":
       "large_shift: In expression 1 << dst_bit_size - 1U, left shifting by
        more than 31 bits has undefined behavior. The shift amount,
        dst_bit_size - 1U, is 4294967295."
