--- Comment #5 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Reduced:
struct A {
A(int a = 0) { }
};
struct B : A {
using A::A;
B(int, int);
};
B b;
FWIW the relevant output from Clang trunk is:
c.cc:10:3: error: no matching constructor for initialization of 'B'
B b;
^
c.cc:6:12: note: candidate constructor (inherited) not viable: requires 1
argument, but 0 were provided
using A::A;
^
c.cc:2:3: note: inherited from here
A(int a = 0) { }
^
EDG says simply:
"c.cc", line 10: error: no default constructor exists for class "B"
B b;
^
