[Voted into WP at October, 2009 meeting.]
7.6.2.6 [expr.alignof] paragraph 1 currently says regarding alignof,
The operand shall be a type-id representing a complete effective object type or a reference to a complete effective object type.
This prohibits taking the alignment of an array type with an unknown bound. There doesn't appear to be any reason for this restriction.
Proposed resolution (July, 2009):
Change 7.6.2.6 [expr.alignof] paragraph 1 as follows:
The operand shall be a type-id representing a complete effective object type or an array thereof or a reference to a complete effective object type.
