[Bug middle-end/32176] [4.3 Regression] ICE tree-type mismatch: expected integer_cst, have plus_expr in int_cst_value, at tree.c:7720

#2  0x0000000000a30ddc in int_cst_value (x=0x2b8d9ea73780)
    at /space/rguenther/src/svn/trunk/gcc/tree.c:7720
7720      unsigned HOST_WIDE_INT val = TREE_INT_CST_LOW (x);
(gdb) call debug_generic_expr (x)
(int8) {2, +, 1}_1 + -1

this is a problem in data-ref analysis.

1761      if (TREE_CODE (chrec) != POLYNOMIAL_CHREC)
1762        return int_cst_value (chrec);

I guess Zdenek exposed this somehow.
