Short description of error
I'm getting a repeatable crash when trying to set position for debug purposes. I'm getting a vector out of a group node and try to use "Set Position" to visualize the vector in the viewport.
Unfortunately I wasn't able to simplify the group more, if I do that, after reloading blender it doesn't crash any more, even though the resulting set position still produces the wrong result.
Exact steps for others to reproduce the error
In the attached scene, please connect the Vector output of the Donut Field group node with the Position input of the "Set Position" node, and blender will crash.
