--- Comment #1 from Jason Merrill <jason at gcc dot gnu.org> ---
Confirmed.
The problem seems to be that free_lang_data_in_decl changes DECL_CONTEXT of
Klass::implementation to be the global scope because it isn't virtual, but
eventually update_vtable_references changes the vtable entry for Klass::magic
to refer to (a local alias for) Klass::implementation, so maybe_record_node's
attempts to ask about its class context fail.
Currently free_lang_data_in_decl works around this issue for destructors
specifically, but not for other member functions.
Not sure if the component should be tree-optimization or lto, but it isn't a
front-end issue.
