I can't reproduce the behaviour on recent builds from trunk.  E.g, on
r182308 I am getting:

$ cat -n test-PR51475.cc 
     1    #include <initializer_list>
     2    
     3    struct A
     4    {
     5        A(int*);
     6    };
     7    
     8    struct B
     9    {
    10        const std::initializer_list<A>& x;
    11    };
    12    
    13    B b = {{1}};

Err, sorry the previous comment was for another bug.  Forget about it.

This should be fixed in trunk (4.7)
