That seems like a good idea and worth pursuing but perhaps I should emphasise that my impression (albeit a 'gut feeling') is that this problem isn't necessarily connected with quark management. What seems to be happening is this:- When a Gtk::SpinButton has a Gtk::Adjustment attached, a time will eventually come when the SpinButton goes out of scope (i.e. gets destroyed). During the destruction process, "something" gets done to the attached Adjustment. AFAICT that "something" doesn't actually destroy the Adjustment - but whatever does get done includes an assumption that the Gtk::Adjustment (if still attached) will still be a valid object. Things go wrong if the Adjustment has already gone out of scope by the time the SpinButton goes out of scope. It's not impossible that there's a connection with quark management but the key to this will be to identify what exactly is "getting done" to the Adjustment during destruction of the SpinButton. If we could identify what's actually getting done, that would probably get us a lot closer to understanding this problem.
