Varjo: Compilation failed

[collinalexbell]

Hi, I am trying to manually run the triangles example.

(defstruct-g pos-col
  (position :vec3 :accessor pos)
  (color :vec4 :accessor col))

(defun-g tri-vert ((vert pos-col))
  (values (vector (pos vert) 1.0)
          (col vert)))

When I attempt to run defun-g, I get
