        <pre>C11 6.7.10/3: "The constant expression shall be an integer constant

expression."


C11 6.6/6: "117)An integer constant expression shall have integer type and

shall only have operands that are integer constants, enumeration constants,

character constants, sizeof expressions whose results are integer constants,

_Alignof expressions, and floating constants that are the immediate operands of

casts. Cast operators in an integer constant expression shall only convert

arithmetic types to integer types, except as part of an operand to the sizeof

or _Alignof operator."


So Clang is correct to reject this.</pre>
