However, if I rewrite the vfunc version to build the UI in the startup method, it segfaults during the Gtk3::ApplicationWindow->new($app) call.

Call SUPER::STARTUP before that; quoting Gtk-3.0→Application→Constructors→new docs:

Concretely, gtk_init() is called in the default handler for the GApplication::startup signal. Therefore, GtkApplication subclasses should chain up in their GApplication::startup handler before using any GTK+ API.

Cheers
