Background info: Pd-l2ork has an extra member at the _end_ of the t_widgetbehavior struct. This member is used to do accelerated displacing of a selection of objects in Pd.
This type of modification isn't meant to be binary compatible in both directions. Your Pd-Vanilla externals with the Vanilla t_widgetbehavior struct will not work in Pd-l2ork, because the struct is smaller.
When Pd-l2ork tries to access those elements off the end of the t_widgetbehavior struct, it should seg fault.
