Summary0002548: Overflow exception in DAGView
DescriptionWhen creating a document dependency graph of a certain structure at once in a script, FreeCAD vanishes (closes with no error message or crash report)
Steps To Reproduce1. Ensure DAGView is enabled.
hint: to enable DAGView, go to Tools->Edit Parameters. Locate folder BaseApp->Preferences->DAGView, set boolean parameter named 'Enabled' to true. Restart FreeCAD. Then, you can find the DAGView window in View->Panels->DAG View (but it's not necessary to have the DAG view displayed for this test)
2. copy-paste this script to Py console:

import FreeCAD as App
import Part
if not App.ActiveDocument:

def killer():
    vertex = App.ActiveDocument.addObject("Part::Vertex","Vertex")
    objs = []
    for i in range(60):
        o.Base = vertex
        o.Dir = App.Rotation(i,0,0).multVec(App.Vector(1,0,0))
    grp = App.ActiveDocument.addObject("App::DocumentObjectGroup", "Group")
    grp.Group = objs


After this script finishes running, FreeCAD almost immediately closes.

The exception causing this was traced in discussion:
"Vanish (crash) probably in DAGView"

Werner has made some changes to exception handling, so the bug probably behaves differently now:
