          Issue ID: 24867
           Summary: Wrong deprecation warning of @system variable usage
                    under CTFE
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: contact at lsferreira.net

```
align(1) struct Bar {
        align(1) const char* name;
}

struct Foo {
    static immutable Bar bar = Bar("foo");

    @safe
    void foo()
    {
        static assert(bar == "foo");
    }
}
```

This raises a deprecation warning, where it shouldn't. This is not a variable
but a constant, its not GC tracked, so alignment doesn't particularly matter.
