Bug Error with raycasting and an AllHitsCollector when Burst is disabled

In my game, there's a point where I do a raycast like this:

Code (CSharp):

1.  
2. RaycastInput castInput = new RaycastInput
3. {
4.     Start = startPoint,
5.     End = startPoint + (direction * length),
6.     Filter = characterPhysicsCollider.Value.Value.Filter,
7. };
8. tmpRaycastHits.Clear();
9. AllHitsCollector<RaycastHit> collector = new AllHitsCollector<RaycastHit>(1f, ref tmpRaycastHits);
10. collisionWorld.CastRay(castInput, ref collector);

When Burst is enabled, everything seems fine. When Burst is disabled, I get these errors:


The assertion that breaks is this:


Visually, the raycast looks like the red line here


When debugging right before the Assert, the "hit.Fraction" is 1f and the "MaxFraction" is 1f.

1. Not sure how clear it is from the image, but the ray does intersect the box collider of the orange surface. In theory, its hit.Fraction shouldn't be 1f
2. Is it intentional that the Assert is using a "<" instead of a "<="?

 

This has come up before and in the latest codebase that assert has been changed to "<=".
I can't remember the details of the top of my head but I'll look up the PR that changed this.
