The hideously long (but apparently valid) call sequence has overflowed the 4kB Xen stack. Given that stacks are only per-cpu on x86 Xen, I should probably just make them bigger (perhaps 8kB on debug builds, 16kB on non-debug builds). 64-bit non-debug builds already have (almost) 8kB stacks, so shouldn't see this crash. 

These crashes are on a 64 bit system.

So yes, even with 8kB stacks it crashes.


But you're running a debug build, so you have a 4kB stack.
