To further explain this -- the padding is added so things like 
pointer arithmetic on an array work.

In my code sample above one can only access the first element 
anyhow so I don't understand why this restriction is imposed here.

struct S
{
    int i;
    bool b;
}

struct T
{
    S s; // reinterpreting this as an array can only access this 
first element anyway
    char c; // so why can't this be aligned directly after `s` 
without any padding?
}
