Bug #: 33159
           Summary: Loading of some copy-protected .dll Files is not
                    working (i.e. activation.dll, awc.dll)
           Product: Wine
           Version: 1.5.25
          Platform: x86-64
        OS/Version: Mac OS X
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

Some .dll Files are packed and stripped of the relocation table in order to
provide some level of protection against dissasemblers. Those files are
commonly found in DRMed Software.

Trying to start Sim City (2013) in wine on OSX will give a "Activation.dll load
failed" Error. Using WINEDEBUG=+map_image you will find the following line in
the logs

4348.132:0009:warn:module:map_image Need to relocate module from 0x40000000 to
0x10d0000, but there are no relocation records

The same Application runs without problems on wine for linux.

On OSX the memory range 0x00075000-0x40075000 is reserved for WINE_DOS on
startup. When the .dll is loaded, the call to wine_mmap_is_in_reserved_area
will indicate that the base-addres of the library (0x40000000) is already
reserved forcing it to relocate to another, free address range. Without the
relocation table this is impossible and results in the above message.
