--- Comment #3 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-05-23 13:22:12 UTC ---
The 1 is non-canonical:

(gdb) call debug_tree ($1)
 <integer_cst 0x7ffff5b25eb0 type <integer_type 0x7ffff5b29540> constant 1>
(gdb) call debug_tree (0x7ffff5b29540)
 <integer_type 0x7ffff5b29540 public QI
    size <integer_cst 0x7ffff7e734d8 type <integer_type 0x7ffff7e860a8
bit_size_type> constant 8>
    unit size <integer_cst 0x7ffff7e73500 type <integer_type 0x7ffff7e86000
long unsigned int> constant 1>
    align 8 symtab 0 alias set -1 canonical type 0x7ffff5b29540 precision 1 min
<integer_cst 0x7ffff5b25690 -1> max <integer_cst 0x7ffff5b256b8 0>>
(gdb) p $1->int_cst.
common   int_cst  
(gdb) p $1->int_cst.int_cst 
$2 = {low = 1, high = 0}

built via build_int_cst, fixed on trunk by properly making that produce
canonical constants.
