--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. We have VR_UNDEFINED as other_op in
#4 0x00000000030c3df4 in gori_compute::refine_using_relation (this=0x490b310,
op1=<ssa_name 0x7ffff643c360 42>, op1_range=...,
op2=<ssa_name 0x7ffff643c678 53>, op2_range=..., src=..., k=VREL_LT)
at /home/rguenther/src/trunk/gcc/gimple-range-gori.cc:1034
1034 if (!op_handler.op2_range (new_result, type,
(gdb) l
1029 src.get_operand (other_op, def_op1);
1030
1031 // Using op1_range as the LHS, and relation REL, evaluate op2.
1032 tree type = TREE_TYPE (def_op2);
1033 Value_Range new_result (type);
1034 if (!op_handler.op2_range (new_result, type,
1035 op1_def_p ? op1_range : op2_range,
1036 other_op, relation_trio::lhs_op2 (k)))
must be a quite recent regression.
