--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
This was fixed at some point:

<stdin>:3:20: error: allocating an object of abstract class type 'A'
void f() { B<A>::f(*(A*)0); }
                   ^
<stdin>:1:25: note: unimplemented pure virtual method 'x' in 'A'
struct A { virtual void x() = 0; };
                        ^
