    libwine: On Mac, disable ASLR for Wine processes. · ecd53057
    Ken Thomases authored
    ASLR can allow dyld to be loaded where it overlaps one of the regions that the
    preloader would like to reserve.  That, in turn, can prevent Wine from using the
    shared user data region.  With ASLR disabled, dyld will be loaded immediately
    after the preloader, which has a defined base address.
    
    This uses an Apple extension to posix_spawn() that allows it to replace the
    calling process's image, like a more featureful execve().  The flag to disable
    ASLR is technically private SPI, but has remained stable for many versions of
    the OS.  And the Mac preloader is already stepping over that line.
