It is not my library, I'm not going to debug it. The example _only_ calls the constructor of a standard class. If it crashes, it is not my fault, but Gtkmm's one.

If the contstructor crashes when invoked from a derived class, that means I practically can't. Did you check the example with modern Gtkmm? Does it crash there too or does it work fine?
