Mark this is fixed on the 4.0 branch, the middle-end part was PR 21595 and was commited to 4.0
branch:
2005-05-27 Richard Guenther <rguenth@gcc.gnu.org>
PR middle-end/21595
* builtins.c (fold_builtin_constant_p): Handle
&"string cst"[0] as constant.
And the testcase here works now.
Were you using an old branch to test on?
