Proposed resolution (August, 2011):

Change 7.7 [expr.const] paragraph 2 as follows:

  • an lvalue-to-rvalue conversion (7.3.2 [conv.lval]) unless it is applied to

    • a glvalue of integral or enumeration type that refers to a non-volatile const object with a preceding initialization, initialized with a constant expression [Note: a string literal (5.13.5 [lex.string]) corresponds to an array of such objects. —end note], or

    • ...

It is not clear whether a string literal can be used in a constant expression.
