             Summary: Use PIMPL, not an interface, for event_loop
                 Key: PROTON-1372
                 URL: https://issues.apache.org/jira/browse/PROTON-1372
             Project: Qpid Proton
          Issue Type: Bug
          Components: cpp-binding
    Affects Versions: 0.14.0
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher
            Priority: Blocker
             Fix For: 0.16.0


If you have a libqpid-proton-cpp compiled with C\+\+11 and then link to it using a C\+\+03 and use the {{proton::container::schedule}} API then the application will crash. This is because there is an extra virtual function present in the middle of the C\+\+11 vtable compared to the C\+\+03 vtable. So that when used from '03 the wrong member function gets called.

The extra member function is present because of conditional compilation dependent on the C\+\+ version doing the compilation.

This should also be a problem the other way round too, so using a libqpid-proton-cpp compiled with C\+\+03 from C\+\+11 will cause there to be one fewer entry in the vtable, and using schedule will either get the wrong version of schedule or call an entry of the end of the vtable.
