Description Joe Groff 2013-11-09 11:08:13 PST 
This code incorrectly warns that the [[clang::falltrhrough]] annotation does not precede a switch label:

void foo(int x) {
  [&]{
    switch (x) {
    case 0:
      foo(0);
      [[clang::fallthrough]];
    case 1:
      foo(1);
    }
  }();
}

Remove the lambda [&]{ }() and the warning goes away.
