          Issue ID: 22329
           Summary: DMD and LDC2 Segumentation Faults due to alias this on
                    private field + special names
           Product: D
           Version: D2
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: msnmancini@hotmail.com

That causes a sigsegfault on DMD without any error message
```d
public struct Foo {
    private int values;
    alias values this;
}

void main()
{
    writeln(Foo());
}
```

If the values variable is changed to "values2", then, a compiler error is being presented.

The mix of private and that special name causes an error, @jrfondren did a brute force test case for every word that happens: https://gist.github.com/jrfondren/78b5d366e37a6a9c4b91e37751f25789

@Mayonix helped me tracking that bug too by getting to the conclusion
"So when you name a private field some function defined in object.d, alias this
it, and then pass an object to a function in a different module which attempts
to access the alias this, it can't access the field in question because it's
private, so instead it finds the function defined in object.d,"
