[Bug ada/15841] New: Illegal program not detected, RM 3.9(17)

-- RM 3.9(17)
-- Given a prefix X that is of a class-wide tagged type
with ada.tags;
package Test_247015 is
   type T1 is tagged null record;
   x: T1;
   y: ada.tags.tag := T1(x)'Tag;   --ERROR: prefix of 'tag must be classwide
end Test_247015;


I expect an error message like this:
test_247015.ads:7:22: "T1(x)" is not a classwide tagged type

But I get nothing.

On the mainline I get: 
test_247015.ads:7:26: "Tag" attribute can only be applied to objects of class-wide type
test_247015.ads:8:16: missing ";"

Is this a correct error?

Note the error about the semicolon was my fault for not copying the semicolon at the end of the line 
but does not matter we still reject it:
test_247015.ads:7:23: "Tag" attribute can only be applied to objects of class-wide type
