If it's really a crack, you're gluing into end grain? Or is it
a split, gluing long grain? Cracks are a hard problem,
splits are less hard, BUT a split might have found a
sap element, glue can easily fail there.

Instead of pinning the joint with metal fasteners, consider
careful boring and fitting of dowels; a glued dowel
across the grain makes a tough reinforcing element.
