Comment (by artegion):

 Not a real problem, just a bit disappointing: python ctypes documentation
 describes an interesting feature but our code presents a different
 behavior (it is far more pythonic do not care about byreference/byvalue if
 ctypes can do the dirty work).

 The odd thing is that happens unnoticed: while ctypes raises exceptions
 passing wrong argument type in this case only function return code (or
 segmentation fault exception) reveals troubles.
