This was caused by my patch:
>       * gimplify.c (zero_sized_type): New function.
>       (gimplify_modify_expr_rhs): If we have a zero sized type,
>       replace the statement with an empty statement.

I had forgot that you could get the side effects on either side of the assignment.

See http://gcc.gnu.org/ml/gcc-patches/2005-08/msg01444.html

note I think we should only expand the side effects and not the assignment.
