Summary: New mmap breaks application loading on FreeBSD
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: FreeBSD
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-loader
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I have just attempted my first upgrade of wine in a couple of weeks (from CVS) 
and on trying to launch various applications I receive errors related to 
mapping addresses. Of particular interest to me is the failure I get trying to 
run Lotus Notes R5 client.  Running wine nlnotes I receive the following 
messages:

fixme:ntdll:NtQueryVolumeInformationFile device info not properly supported on 
this platform 
fixme:file:get_default_drive_device auto detection of DOS devices not 
supported on this platform 
fixme:cdrom:CDROM_GetInterfaceInfo not implemented for BSD 
err:virtual:map_image Image was mapped at 0x205d0000: standard load address 
for a Win32 program (0x00400000) not available 
err:virtual:map_image Do you have exec-shield or prelink active? 
wine: could not load L"C:\notes\nlnotes.exe" as Win32 binary

Apparently at version 1.9 of loader/main.c, some code was removed that changed 
the way memory was mapped, and the workaround for this was basically to revert 
to version 1.89 (this is what the FreeBSD port does).  It seems that in the 
last few days some new functionality was added to libwine to handle this, and 
a new file, mmap.c, was added in libs/wine.  I am assuming this is where the 
failure is, but I don't yet have an understanding of how this code works.  Can 
anyone help with this?
