Initialising an union

[Aurel Balmosan <ab@orga.com>]

Hello,

I noticed a problem while initialising an union.
Here a test source:

struct a {
        int a;
};

struct b {
        int a;
        double b;
};

struct c {
        int a;
        double b;
        char c[16];
};

union x {
        int a;
        struct a as;
        struct b bs;
        struct c cs;
};

void test()
{       union x X = { 0 };
        for(;;);
        X.a++;
}

void main()
{       char    c[]="1123124213";
        test();

}

You will notice that the union X is not fully initialised. At least I noticed
that
on DecUNIX-4.0b (4.0d) Solaris-2.5.1 with the egcs version

  egcs-2.90.29 980515 (egcs-1.0.3 release)
