OK, I have a little more detail on this. I misread the error, it turns out that the StackLoad error doesn't occur while saving a continuation for debug. Those are getting saved and I can debug them in GemTools. The error is apparently triggered when trying to run a callback.
Here's the full stack, relevant section emphasized:
----------- Continuation saved to object log ERROR Encountered: 2014-07-17T11:43:56.08789706230164-07:00
a ImproperOperation occurred (error 2252), Error 'in StackLoad' , 'saved stack is LinuxX86_64, process switch expects interpreted' . Execution cannot continue.

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.
