Binary version, steps to reproduce:

  • Create 2 Blueprints classes derived from Actor
  • Give each BP a spline component
  • Inside the Blueprint details of one of those classes, click on a random spline point
  • Close the details view
  • Open the details of the other Blueprint class and again click on a random spline point
  • Boom!

Error message:

Access violation - code c0000005 (first/second chance not available)
