> The constant representing the size of the metadata is defined as a unsigned
> int variable with 32-bit.
> Similarly the constant representing the maximal output is also defined as a
> unsigned int variable with 32-bit.
> 
> There is potentially overflowing expression when those constants are
> evaluated using 32-bit arithmetic, and then used in a context that expects an
> expression of type size_t (64 bits, unsigned).
> 
> Change the size of the above constants to 64-bit.
