------- Comment #1 from pinskia at gcc dot gnu dot org 2007-03-25 08:46 -------
This is a front-end issue:
<<cleanup_point <<< Unknown tree: expr_stmt
(void) (a = TARGET_EXPR <D.2077, <<cleanup_point TARGET_EXPR <D.2076, <<<
Unknown tree: aggr_init_expr
4
__comp_ctor
D.2076
0B >>>
>>>>) >>>
We have a cleanup_point expression which causes an extra variable to be created
but since the type is addressable, we abort.

P2, rather than P1, because of the use of statement-expressions.
