sserver will crash after mining.authorize in a 32bit OS

[SwimmingTiger]

BTCPool has never been run on 32-bit operating systems, so we do not know if it is compatible with 32-bit systems.

But now we have a case. A BTCPool built and run in a 32-bit Ubuntu 16.04 and shows it is not compatible with 32-bit operating systems.

In this case, every thing is OK but sserver. The sserver can start, listen, and receive connections, until a miner to request authorization.

I will not fix this issue because I do not need to run BTCPool on a 32-bit operating system.

BTCPool is only tested in 64-bit operating systems. I recommend that anyone who wants to run BTCPool choose a 64-bit operating system.
