Using int is easy to result in memory overflow on Linux.

@lxzan Can you please explain how int can lead to memory overflow on Linux? Or give some links, please. I also want to understand this.

Sorry, my stupid student using32-bit compiler with 64-bit OS leads to the problem. I asked him for times if his env is right and he's sure. Int is 32 bit on 32-bit OS, while 64 bit on 64-bit OS. Please ignore my PR.

@Ixzan It's not an invalid PR. The bug is really, causing the code to not build on 32 bit platforms.

This is a real bug, occurring when the package is used on 32 bit platforms. Please reopen.

@Ixzan Perhaps a project member has to do that.

@VadimKulagin Could you reopen this one?

The problem is that UNSERIALIZABLE_OBJECT_MAX_LEN overflows a 32 bit integer, which is the size of an int on 32 bit platforms.

@clausecker I don't have that button unfortunately.

I think that either the project owner can reopen this issue, or a new one can be created.
