[Voted into the WP at the September, 2008 meeting.]
The specification for the alignof operator (7.6.2.6 [expr.alignof]) does not forbid function types as operands, although it probably should.
Proposed resolution (March, 2008):
The issue, as described, is incorrect. The requirement in 7.6.2.6 [expr.alignof] is for “a complete object type,” so a function type is already forbidden. However, the existing text does have a problem in this requirement in that it does not allow a reference type, as anticipated by paragraph 3. Consequently, the proposal is to change 7.6.2.6 [expr.alignof] paragraph 1 as indicated:
An alignof expression yields the alignment requirement of its operand type. The operand shall be a type-id representing a complete object type or a reference to a complete object type.
