26143     if (op2 == op1 || operand_equal_p (op2, op1, 0))
(gdb) p debug_generic_expr (op2)
(char *) &(d != 0 ? b : c).c
$3 = void
(gdb) p debug_generic_expr (op1)
(char *) &(d != 0 ? b : c).c

        case COND_EXPR:
        case VEC_COND_EXPR:
        case DOT_PROD_EXPR:
          return OP_SAME (0) && OP_SAME (1) && OP_SAME (2);

obviously address-of should be masked for op0 of COND_EXPR.

Testing a patch.
