reference to function arguments fails inside list comprehension

What steps will reproduce the problem?

def argument_comprehension(i, j, k):
  ijk = [i,j,k]
  arg_comp = [arg for arg in [i,j,k]]
  #arg_comp = [arg for arg in ijk] #working alternative
  return arg_comp
a = argument_comprehension(1,2,3)
assert a == [1,2,3],  'instead arg comp failure as %s'%a
print('Ok')

What is the expected output? What do you see instead?
Ok

Instead:
AssertionError: instead arg comp failure as [3,4,3]
module '__main__' line 7
assert a == [1,2,3],  'instead arg comp failure as %s'%a

What version of the product are you using? On what operating system?
Brython version 1.1.20130317-111626
Linux Mint 14 Nadia - Firefox 19.0.2

Please provide any additional information below.
works ok in Python 3.2.3 
or in Brython when working alternative line is uncommented
