Unknown term reference: null

[lJoublanc]

Describe and demonstrate the bug
Referencing FFI.Ptr.null results in the aforementioned compiler error.

Environment (please complete the following information):

• ucm --version 1.1.0
• OS/Architecture: Ubuntu Linux

Additional context
When I do an ls lib.base.FFI.Ptr I see:

  18. null     (type missing)
  19. null.    (1 term)

Which seems a bit suspicious.

Also, this may be related to #6200

Just upgrade to 1.1.1 and you should be good! That is the release that added null pointers in FFI.
