If size_t is passed or stored in Lua then it is possible that by default Lua
can not represent all the values of size_t. The size of size_t is
implementation defined yet it is _normally_ 32 bits on x86 and 64 bits on
x86_64 yet the implementation can use any value greater or equal to 2 ^16
-1. If you want to allow Lua to use the full range of a 64 bit number then
you have to modify the core[1], the other option is to remove any type which
can be 64 bits on an arch and instead use sized types.
