This looks like it's in the code I changed for compatibility with the new ABI. Gorm is now using reflection to find private ivars in GNUstep, rather than accessing them directly (accessing private ivars in the new ABI will now cause a link failure anywhere other than the compilation unit containing the @implementation).

If this assertion fails, it means that the Objective-C compiler / runtime that you are using is not able to find reflection metadata for the _window ivar in NSDocument. This is quite worrying, because looking up ivars via the reflection APIs worked even back in the GCC 3.x days.
