[Glass] Error in StackLoad

We've recently moved our application to a new server, and my Zinc gems are crashing when continuations are saved:
> a ImproperOperation occurred (error 2252), Error 'in StackLoad' , 'saved stack is LinuxX86_64, process switch expects interpreted' . Execution cannot continue.
This wasn't happening on the old server, and configs are identical as far as I can tell. I disabled native code in the gem, thinking that'd help, but it made no difference. In a way, I'm glad about that because I really want to use native code in production... but now I'm at a loss as to where this error is coming from.
We're still on 3.1.0.4. The new server is Debian 7, while the old one was Ubuntu 12.04.4 LTS. Kernels are essentially the same (3.2.0). Both the old server and the new server are cloud instances, old was at Rackspace with AMD processors, and the new is at Amazon with Intel Xeons.
