--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
The test() call is represented as *(volatile struct A *) this, A::test () and
the *this dereference in that case is what triggers the error (well, this
itself).
This is created by:
8827 /* In an expression of the form `a->f()' where `f' turns
8828 out to be a static member function, `a' is
8829 none-the-less evaluated. */
8830 if (TREE_CODE (TREE_TYPE (fn)) != METHOD_TYPE
8831 && !is_dummy_object (instance)
8832 && TREE_SIDE_EFFECTS (instance))
8833 call = build2 (COMPOUND_EXPR, TREE_TYPE (call),
8834 instance, call);
So shall we have some exception of *this if it is volatile and still ignore it?
