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.
