The problem with GetMaxU64 is that it always returns uint64_t even though actual type was uint32_t, so when byteswap is performed it becomes invalid integer, to fixed this we need to store correct bitwidth not higher.
i.e.
Suppose there is actual 32 bit integer i.e. 0xffffffff
`GetMaxU64` will return 0x00000000ffffffff (prmoted to uint64_t from uint32_t)
 and when performing byteswap on this it becomes 0xffffffff00000000 which is invalid.
