        <div>
        <pre>When attempting to instantiate an abstract class clang returns:

test.cc:18:5: error: variable type 'A' is an abstract class
  A a;
    ^
test.cc:4:16: note: unimplemented pure virtual method 'a' in 'A'
  virtual void a()=0;

The second line claims that A::a() is unimplemented.  It does this even if you
include an implementation.  This is incorrect and potentially misleading.

struct A {
  virtual void a()=0;
};

void A::a() {}

int main() {
  A a;
}</pre>
