Description:
I have synergy (1.4.15-1) running as server on arch, and a synergy (1.4.15) client on a mac.

The server starts without any problems, but when the client tries to connect the server stops. From journalctl:
Nov 19 11:45:37 nunki kernel: traps: synergys[4646] trap invalid opcode ip:5e67e0 sp:7fff00b514b8 error:0 in ...dd000]
Nov 19 11:45:37 nunki systemd-coredump[4649]: Process 4646 (synergys) dumped core.

This set up used to work before synergy was updated to version 1.4.15-1.

Additional info:
synergy 1.4.15-1
Linux 3.12.0-1-ARCH #1 SMP PREEMPT Wed Nov 6 09:06:27 CET 2013 x86_64 GNU/Linux

Hitting this as well on a 1-day old install of Arch Linux. The backtrace looks like it's something coming out of Crypto++ but maybe I'm misreading the backtrace (I'm not a C/C++ programmer).
