I didn't test your test code but the address of your node is
non-existant on the current x86_64.  try:

	cat /proc/self/maps

on your pc to see where is mapped.

it is impossible to get bus error with un-aligned address on x86 cpu
unless you enable the check. see:

       http://en.wikipedia.org/wiki/Segmentation_fault#Bus_error

it might be good idea to check how lookup_type_node_I() works with
tinycc.

have fun.
