--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
The issue is we fail to gimplify type sizes properly:
fn1 ()
{
extern void fn2 (int[0:(sizetype) ((long int) SAVE_EXPR <fn3 ()> + -1)] *);
}
happens when we try to output the function type of fn2. Bug in the frontend,
a DECL_EXPR is missing here.
