Erroneous code using anonymous variables and constructors.

[Ludovic WALLE]

The execution of the following code compiled with gcc:

    struct x    { int       i; };

    int     main ()
    {
        struct  { struct x  *x; } a = { &((struct x) { 123456 } ) };
        struct  { struct x  *x; } b = { &((struct x) { 123456 } ) };
        struct  { struct x  *x; } c = { &((struct x) { 654321 } ) };

        printf ("a.x: %p\n", a.x);
        printf ("b.x: %p\n", b.x);
        printf ("c.x: %p\n", c.x);
        return (0);
    }

generates the following output:

    a.x: 400010e0
    b.x: 400010e0
    c.x: 400010e4

The struct x of variables a and b are the sames (same address) but they 
shouldn't. They are different only if the initialisation value is 
different (variable c).
Anonymous variables with the same initialisation seems to be abusively 
merged .


I compiled the code with no options at all (gcc f.c).
gcc -v gives:
