Bug ID: 64856
Summary: Initializing struct not accepted in gnu99
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
struct A {
unsigned long b;
};
struct B {
struct A c[2];
};
struct B d = { .c = { [0 ... 1] = (struct A){ .b = -1UL } } };
$ ./cc1 -quiet j.c -std=gnu90
$ ./cc1 -quiet j.c -std=gnu99
j.c:9:35: error: initializer element is not constant
struct B d = { .c = { [0 ... 1] = (struct A){ .b = -1UL } } };
^
j.c:9:35: note: (near initialization for ‘d.c[0]’)
j.c:9:35: error: initializer element is not constant
j.c:9:35: note: (near initialization for ‘d.c[1]’)
This is bad with gnu11 as a default.
