Internal error on preinitialised PNimrodNode variable declaration in recursive macro

[ddlsmurf]

import  macros

macro test*(a: stmt): stmt =
  proc testproc(recurse: int) =
    echo "Thats weird"
    var o : PNimrodNode = nil
    echo "  no its not!"
    o = newNimNode(nnkNone)
    if recurse > 0:
      testproc(recurse - 1)
  testproc(5)

test:
  "hi"

If you remove the = nil, or replace it with newNimNode(nnkNone) it works...

Fails with
Error: test_case_of.nim(6): internal error: evalAux: nkNone
