--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Reduced testcase:
struct S { int s; };
void
foo (void)
{
void *p = &(struct S) { 0 };
void *q = &({ (struct S) { 0 }; });
}
The p initializer is accepted, q is rejected.
By my reading this is invalid, C99 6.5.2.5/6 says:
"If the compound literal occurs outside the body of a function, the object
has static storage duration; otherwise, it has automatic storage duration
associated with the enclosing block."
and the statement expression is still a compound statement and thus the
compound literal is associated with the statement expression's block. So it is
the same thing as:
void
bar (void)
{
void *r = &({ int a = 0; a; });
}
which fails with the same diagnostics.
Joseph, do you agree?
