I guess you are still talking about gtkmm 2.2, rather than glibmm/gtkmm
2.4, right?

To test that theory you would have to try it with a previous version of
gtkmm. I don't think any code for that has changed. Maybe you are using
a different version of the compiler now?


Someone reported this in bugzilla already, but I can't find it now. I
think I closed it, saying that function pointers are particularly
strange, and you can't expect to cast them around like that.

Maybe a templated version of that method would work in gtkmm 2.4.
