        * varasm.c (narrowing_initializer_constant_valid_p): Add CACHE
        argument, call initializer_constant_valid_p_1 instead of
        initializer_constant_valid_p, pass CACHE to it, return NULL
        immediately if first call returns NULL.
        (initializer_constant_valid_p_1): New function.
        (initializer_constant_valid_p): Use it.

        * g++.dg/parse/limits-initializer1.C: New test.
