Hello,

the target (game) has much fewer shared libraries loaded in its early stage as
it was initially created suspended.
In contrast: the loader is fully initialized and has lots of X dependencies at
this point giving addresses spaces a different layout.

Looking at the corresponding kernel32 locations:

Loader:

There is not much you can do.
Moving "locale-archive" is most likely not possible as this is glibc internal
(mmap'd) and not a standard ELF binary which could be relocated (using prelink
etc).

Can't you just get rid of the GUI stuff that pulls in the multitude of shared X
libs?
Making loader a console app might possibly fix this, giving both address spaces
a similar layout without having OS loader moving/relocating much stuff around.
