--- Comment #2 from Sebastian Pop <spop at gcc dot gnu.org> ---
Jump threading is called twice as two separate passes, the "miscompiled" jump
thread during the first invocation is:
 Registering FSM jump thread: (10, 114) incoming edge;  (4, 93) nocopy;

The "miscompiled" jump thread for the second invocation of dom is:

 Registering FSM jump thread: (102, 6) incoming edge;  (5, 128) nocopy;
