------- Comment #1 from pinskia at gcc dot gnu dot org 2009-12-30 19:47 -------
The front-end already changed it into being = {};, a[0] = ...
<<cleanup_point int v[4] = {};>>;
<<cleanup_point <<< Unknown tree: expr_stmt
<<< Unknown tree: expr_stmt
v[0] = a >>>
;
<<< Unknown tree: expr_stmt
v[1] = b >>>
;
<<< Unknown tree: expr_stmt
v[2] = c >>>
;
<<< Unknown tree: expr_stmt
v[3] = d >>>
; >>>
>>;
I thought there was a duplicate of this bug somewhere.
