2760 :: Enum and repr prints invalid data

  Hi

  There seems to be an issue with repr on returned stack objects containing enums. See example below.

  If I create the Ret object in local stack frame, it works. If I change Ret.data to uin32 it works even if returned from a function.

  type
    Status = enum
      Ok, Error
    
    Ret = object
      status:Status
      data:uint8
  
  proc test():Ret =
    return Ret(status:Ok,data:0)
  
  let a = test()
  echo "a ", a         # Ok
  echo "a ", repr(a)   # Prints "invalid data" for the status field
  Run

  Same example but with all cases added.

  I noticed while working on this example that the issue would disappear and surface again simple by changing the object and function names (no semantic difference). But this version is tested and shows the issue

  type
    Status = enum
      Ok, Error
    
    Ret8 = object
      status:Status
      data:uint8
    
    Ret32 = object
      status:Status
      data:uint32
  
  proc test8():Ret8 =
    return Ret8(status:Ok,data:0)
  
  proc test32():Ret32 =
    return Ret32(status:Ok,data:0)
  
  let local = Ret8(status:Ok,data:0)
  echo "local ", repr(local)     # Ok
  
  let a = test8()
  echo "a ", a                   # OK
  echo "a ", repr(a)             # Error
  
  let b = test32()
  echo "b ", b                   # OK
  echo "b ", repr(b)             # OK
  Run
