--- Comment #1 from Jakub Jelinek ---
Can't reproduce in my bisect seed, so can't bisect. Can reproduce with current

7188 clock = INSN_SCHED_CYCLE (insn);
7189 cost = (last_clock == -1) ? 1 : clock - last_clock;
7190
7191 gcc_assert (cost >= 0);
clock is 0, last_clock is 37, so cost is -37.
Though, s_i_d array has just length of 52 and insn here (created by
