URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=170365
Log:
PR c++/47207
* decl2.c (decl_constant_var_p): A constexpr var needs an
initializer to be constant.
* semantics.c (cxx_eval_constant_expression): Complain about
constexpr var used in its own initializer.
* call.c (set_up_extended_ref_temp): Set
DECL_INITIALIZED_BY_CONSTANT_EXPRESSION_P too.
