This is an unofficial snapshot of the ISO/IEC JTC1 SC22 WG21 Core Issues List revision 112e. See http://www.open-std.org/jtc1/sc22/wg21/ for the official list.
The requirement in 6.8 [basic.types] that a literal type must have a constexpr constructor has caused signficant problems with respect to defaulted default constructors, since the determination of whether a constructor is constexpr depends on its definition and a defaulted special member function is only defined if it is odr-used. It might be better to remove that requirement, at least as it applies to defaulted default constructors.
Rationale (September, 2013):
This issue duplicates issue 1360.
