------- Comment #9 from pinskia at gcc dot gnu dot org 2005-10-27 21:15 -------
This is a combination of a GCC extension (of cast to union) and a C99 feature
(subscripting a non-lvalue array) so this is valid code (but undefined code)
even though it looks so weird.
Anyways I have a patch which I am testing.
