--- Comment #10 from Ville Voutilainen <ville.voutilainen at gmail dot com> ---
This code fails with the current trunk:

struct B {};
struct D : B {D(B b) : B{b} {}};


base-aggr-init.cpp: In constructor ‘D::D(B)’:
base-aggr-init.cpp:2:27: error: too many initializers for ‘B’
 struct D : B {D(B b) : B{b} {}};
                           ^

As far as I can see, the function process_init_constructor_record in typeck2.c 
emits the diagnostic.
