--- Comment #2 from David Binderman <dcb314 at hotmail dot com> --- I am getting git bisect results which indicate either commit cb1a4876a0e724ca3962ec14dce9e7819fa72ea5 or commit ba97b532604815333848ee30e069dde6e36ce4c9 is at fault. Neither seem anything to do with C++ or the optimizer, so I must have made a mistake somewhere. Assistance sought.
