--- Comment #3 from David Malcolm ---
It's failing the assertion for a NULL edge at line 175:
#1 0x01644fa1 in begin_move_insn (insn=0x71a4a1f8,
last=0x718c1a00) at ../../src/gcc/sched-ebb.c:175
175 gcc_checking_assert (BARRIER_P (x));
(gdb) list
170 {
171 rtx_insn *x = NEXT_INSN (insn);
172 if (e)
173 gcc_checking_assert (NOTE_P (x) || LABEL_P (x));
174 else
175 gcc_checking_assert (BARRIER_P (x));
176 }
with a code_label, rather than a barrier:
(gdb) call debug (x)
(code_label 20 19 21 4 (nil) [2 uses])
