xen_set_pte() is in the kernel rather than Xen so e.g. from
http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-log-01-with-highpte.txt:
[...]
EIP: 0061:[<c0405d63>] EFLAGS: 00010296 CPU: 0
[...]

Can you use gdb to find out what 0xc0405d63 is, e.g. with "list
*0xc0405d63" and/or "disas 0xc0405d63"

Trying a debug=y Xen might be interesting as well though, it does more
checks etc so perhaps we can spot something odd earlier. Also all my
repro attempts were with debug=y so it would be interesting to know what
happens for you.

Ian.
