This will be won't fix. Wine is bound to windows address space. And it have to
"protect" it from anything else taking it. Like all the shared libraries for
example.

Wine uses preloader to map most of the lover 2GB of address space for it's
needs. Preloader is a minimalistic program that does not use glibc to avoid
loading of any shared libraries.

The reason preloader was written, is to cope with new address randomization
security feature of some distros (now all distros using this). All and I repeat
all windows programs load at fixed address. If that address unavailable
programs just crash / refuse to run. Programs that are compiled to load at
fixed address can not be relocated. That's just the way it is.

Also there are several "special" address spaces that are reserved for "system
use". Again, some programs use these hard-coded addresses to access some system
structures (like Shared User Data). Again this can not be relocated.


The only way to "reserve" address space required by Wine is to .. map it. This
is what you have virtual memory for...
