Well, I've tried that now, and got this:

(XEN) domain_crash_sync called from entry.S (ff147f35)
(XEN) Domain 1 (vcpu#0) crashed on cpu#1:
(XEN) Assertion '(diff != 0) || VM86_MODE(regs) || !RING_0(regs) ||
HVM_DOMAIN(current)' failed, line 35, file x86_32/traps.c
(XEN) BUG at x86_32/traps.c:35

(changeset 9137)

cheers,

  Gerd
