------- Comment #6 from rguenth at gcc dot gnu dot org 2007-08-20 09:44 -------
Which is because...
TREE_OPERAND (pos, 1) = fold_build2 (PLUS_EXPR, itype,
fold_convert (itype,
TREE_OPERAND (pos, 1)),
fold_convert (itype, delta));
fold_convert (itype, -1) generates the overflow as -1 is unsigned and itype
(from TYPE_DOMAIN of the array type) is a signed type.
I'll think about this one.
