Subject: [9fans] Don't Plan 9 C compiler initialize the rest of member of a struct?
Date: Tue,  2 Apr 2019 00:32:35 +0900	[thread overview]
Message-ID: <CAFMepcn3NR=phN=yp3Y0qeQ12jf40_Q_1krVZUm=2-bUCcMYOw@mail.gmail.com> (raw)

Hi, 9fans. I use 9legacy.

About below program, I expected that flags field will initialize to
zero but the value of flags was a garbage, ex, "f8f7".
Is this expected?

```
#include <stdio.h>

struct option {
    int n;
    char *s;
    int flags;
};

int
main(void)
{
    struct option opt = {1, "test"};
    printf("%d %s %x\n", opt.n, opt.s, opt.flags);
    return 0;
}
```
