[Bug 16779] New: Wine always crashes when drive_c is a symlink

http://bugs.winehq.org/show_bug.cgi?id=16779

Summary: Wine always crashes when drive_c is a symlink
           Product: Wine
           Version: 1.1.12
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Hi! I was running Wine 1.1.12 without problems on my Ubuntu 8.10 x64 desktop,
when i decided i wanted my drive_c to be on another drive which has more space
available. But after i moved the drive_c and symlinked it, i could no longer
launch any application - not even winecfg! It always crashes with a page fault.

Steps to reproduce:

1. rm -rf ~/.wine
2. winecfg (creates fresh .wine dir)
3. Install Winamp (works)
4. mv ~/.wine/drive_c /jfs/drive_c
5. ln -s /jfs/drive_c ~/.wine/drive_c
6. Launching "winecfg" results in page fault:

---
vortex@vortex-desktop:/jfs/drive_c/Program Files/Winamp$ padsp wine winamp.exe
wine: Unhandled page fault on write access to 0x004502e6 at address 0x7bc46c61
(thread 001b), starting debugger...
wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart.

Notes:
- I'm not sure if its the symlink or JFS which is bugging Wine.
- The permissions of /jfs and /jfs/drive_c are 777; owner is set to my user
account.
- Both my root filesystem and the /jfs (seperate filesystem) mounts are JFS
volumes.
- /etc/fstab snippets:

# /dev/sda1 = data partition (mounted /jfs)
/dev/sda1       /jfs            jfs     user,relatime,errors=remount-ro 0      
1
# /dev/sda5 = system partition (mounted /)
UUID=5347c06f-5619-41b7-a0db-d6ec096c9ab4 /               jfs    
relatime,errors=remount-ro 0       1

Any pointers on how to provide debug/trace/coredump information are welcome.
