Starting Blender with --enable-new-depsgraph , enables the new dependency graph that's going be default in 2.8.
It allows using certain constraint combinations that are broken/lagged in default/current dependency graph.
For example targeting rig1.bone1 to rig.2.bone.1 while also targeting rig.2.bone.2 to rig.1.bone.1
will cause the bones to get stuck/overshot/offset from what seemed like the obvious intended transformation.


Anyway, Blender just crashes, and in the command prompt, these were left:

SMD IMPORTER: now working on orcfemale_earrings1
- This is a mesh
- Imported 116 new bones
- Imported 1 frames of animation
Error: EXCEPTION_ACCESS_VIOLATION

Happens on everything, and disabling import animation still says imported animation before crash. new depsgraph works in 2.78c (and I believe it worked in the daily 2.78.5 builds) but now in 2.79 it crashes.
