it's ICEing because host_integerp complains that TREE_OVERFLOW is set:
#1 0x084f7397 in tree_low_cst (t=0x4022daf8, pos=1) at tree.c:4273
Line number 4273 out of range; tree.c has 2318 lines.
(gdb) call debug_tree(t)
<integer_cst 0x4022daf8 type <integer_type 0x4019c78c> constant invariant
public static overflow 0>
