        * constexpr.c (maybe_constant_init_1): New function.
        (maybe_constant_init): Make it a wrapper around maybe_constant_init_1.
        (cxx_constant_init): New function.
        * cp-tree.h (cxx_constant_init): Declare.
        * typeck2.c (store_init_value): Call cxx_constant_init instead of
        cxx_constant_value.  Move the maybe_constant_init call under an 'else'.

        * g++.dg/cpp1z/constexpr-83692.C: New test.
