If I remember correctly the noinit attribute must also be specified so that initialization doesn't overwrite the string value created by the compiler. In the case of _NEW the compiler has no chance to set the value and th noinit attribute also prevents writing during initialization so the string would naturally contain random memory content.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Dears atribute instance path works in static class instances.
In instances created via __new not assign any name (as it had to be).
But if that instance creates another instance via __new, the name field is filled with extrange characters, not empty.
