--- Comment #1 from Terry Guo <terry.guo at arm dot com> ---
I did a little investigation and think the issue may be related to following
code from function remove_some_program_points_and_update_live_ranges:
782 max_regno = max_reg_num ();
783 for (i = FIRST_PSEUDO_REGISTER; i < (unsigned) max_regno; i++)
784 {
785 for (r = lra_reg_info[i].live_ranges; r != NULL; r = r->next)
786 {
787 lra_assert (r->start <= r->finish);
788 bitmap_set_bit (born, r->start);
789 bitmap_set_bit (dead, r->finish);
790 }
791 }
The max_regno is 575, while the length of array lra_reg_info is just 568. When
the loop index i is 568, the issue is triggered.
