Is this a compiler bug?

[Stefan_Salewski]

Based on recent report of Simon, I did a short test:
    
    
    type
      OP = ptr O
      O = object
        i: int
    
    proc int(o: OP): int =
      0
    
    var j: int
    var k: int8 = 0
    
    j =  int(k)
    
    
    
    
    nim c  t.nim
    Hint: used config file '/home/stefan/Nim/config/nim.cfg' [Conf]
    Hint: system [Processing]
    Hint: t [Processing]
    t.nim(12, 9) Error: type mismatch: got (int8)
    but expected one of:
    proc int(o: OP): int
    
    nim -v
