http://bugs.winehq.org/show_bug.cgi?id=14636

           Summary: Catia often can't open files
           Product: Wine
           Version: CVS/GIT
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: ntdll
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: mah at jump-ing.de


Catia (http://appdb.winehq.org/objectManager.php?sClass=application&iId=6153)
often can't open simple files (.CATParts) If you attempt to do so, the app
locks in about 80% of the attempts and throws an Visual C++ runtime exception
with code 0x80000003 (intentional jump to the debugger).

As this bug doesn't appear reliable, it appears to be some sort of race
condition. A lot of these messages appear reliably, though:

  fixme:ntdll:NtLockFile I/O completion on lock not implemented yet

Possibly, Catia uses NtLockFile()'s 4th argument to ensure file read
synchonisation. I have no idea how to find this out, though.
