Well, that was the reason for the '--noaslr' switch in rebaselst, which can
be activated by the peflags argument to rebase-trigger.  However, in the
case of emacs-x11 I've just tested ASLR allowed it to work through what
would otherwise have been a fork-abort, so it might help to relieve some
pressure on the adress space layout.  I don't think it's a good idea to try
adding the libraries in the Windows system directory to the rebase map and I
have even less ideas on how to prevent Windows from putting it's own DLL in
the "rebase space" when X11 starts up...


Regards,
Achim.
