It is not gone. Problem is allocating that section of memory is needed so
particular programs work. Wine is just getting more selective. If you run
programs that will never call that space it is being attempt to avoid allocating
that memory.
In the past wine was always allocating the space if it was needed or not.
Wine is just getting smartter. So expect to see it again some time.
Also that is a warning not a error. Lot of applications use to work with the
warning reason they did not truly need that memory space. If detection of what
applications need and don't need that memory space gets great that message
might upgrade from a warning to a error.
