I don't get why this is WAITING, if you have suggestions on how to improve the
diagnostic, please REOPEN. Otherwise this is not a bug.

Clang prints something similar:

/tmp/webcompile/_26316_0.cc:11:5: error: no viable overloaded '='
  x = f();
  ~ ^ ~~~
/tmp/webcompile/_26316_0.cc:3:6: note: candidate function not viable: no known
conversion from 'X' to 'X &' for 1st argument
  X& operator=(X&);
     ^
1 error generated.
