------- Comment #7 from jason at gcc dot gnu dot org 2010-07-07 13:24 ------- That thread does help, thanks. But part of my confusion was that the testcase you added with that patch (abi/covariant1) didn't actually seem to test the bug. When I add a definition of c14::f17, the test starts failing; even 3.4 refers to the no-this-adjustment covariant thunk in the c14 vtable. So I'm not sure what the patch was actually doing.
