Bug ID: 94225
Summary: C18 conformance for structure implicit initialization
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Keywords: wrong-code
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dje at gcc dot gnu.org
Target Milestone: ---
Example 12 in section 6.7.9 of the C18 standard demonstrates that implicit
initialization does not override prior explicit initialization. The following
is the example code with error checking added.
$ cat example12.c
#include <stdio.h>
struct T {
int k;
int l;
};
struct S {
int i;
struct T t;
};
struct T x = {.l = 43, .k = 42, };
int main(void)
{
struct S l = { 1, .t = x, .t.l = 41, };
if (l.t.k != 42)
fprintf(stderr, "l.t.k is %d instead of 42\n", l.t.k);
}
$ ./xgcc -B./ -std=gnu1x example12.c
$ ./a.out
l.t.k is 0 instead of 42
