This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 110b. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
[Voted into the WP at the March, 2011 meeting as part of paper N3262.]
The current treatment of constexpr constructors and constant expressions does not deal with the initializers for non-static data members, which should also be required to be constant expressions.
Proposed resolution (November, 2010) [SUPERSEDED]:
Change 188.8.131.52 [basic.start.static] paragraph 2 as follows:
if an object with static or thread storage duration is initialized by a constructor call, if the constructor is a constexpr constructor, if all constructor arguments are constant expressions (including conversions), and if, after function invocation substitution (9.2.6 [dcl.constexpr]), every constructor call and full-expression in the mem-initializers is a constant expression
Change 6.8 [basic.types] paragraph 10 as follows (wording assumes the proposed resolution of issue 981)
A type is a literal type if it is:
a scalar type; or
a class type (Clause 11 [class]) that
has a trivial destructor,
is an aggregate type (9.4.2 [dcl.init.aggr]) or has at least one constexpr constructor or constructor template that is not a copy or move constructor, and
has all non-static data members and base classes of literal types; or
an array of literal type.
