--- Comment #1 from Segher Boessenkool <segher at gcc dot gnu.org> ---
It doesn't fail for me, -misel, either -m32 or -m64, either -O2, -Os, -O3,
not with trunk and also not with four weeks ago.
Ah. With -mcpu=8548 it segfaults.
It is some unbounded recursion:
#62 0x000000001118bd14 in fold_rtx (x=0x3fffb6bf2130, insn=insn@entry=0x0)
at /home/segher/src/gcc/gcc/cse.c:3411
Joy, corrupted stack. "x" seems to be some isel (no surprise really),
probably this one (because it's the only isel in the whole program):
(insn 22 21 23 5 (set (reg:SI 137)
(if_then_else:SI (eq (reg:CC 138)
(const_int 0 [0]))
(const_int 0 [0])
(reg:SI 139))) "81288.c":8 330 {isel_signed_si}
(nil))
Anyway, confirmed.
