[Samba] 2.2.7a panic with VFS Audit when writing file (reading is ok)

[Chris Shenton]

Running SAMBA 2.2.7a compiled with Audit support, enabled on a share:

    [global]

    workgroup               = HCAT
    server string           = Samba Server for HCAT
    hosts allow             = xxx.xxx. yyy.yyy.yyy.
    load printers           = no
    log file                = /var/log/log.%m
    max log size            = 50
    security                = user
    encrypt passwords       = yes
    socket options          = TCP_NODELAY
    interfaces              = zzz.zzz.zzz.zzz
    dns proxy               = no

    [sts107]

      browseable            = yes
      writeable             = yes
      path                  = /home/samba/hcat
      inherit acls          = yes
      inherit permissions   = yes
      #
      vfs object            = /usr/local/lib/samba/audit.so


When I connect to it -- with smbclient or windows -- it works until I
try to write (create) a file, then it panics.  smbclient reports:


    smbclient //epsilon/sts107 -W hcat -I epsilon.hq.nasa.gov -U cshento8
    [change dirs]
    smb: \STS107\> put /home/cshenton/.emacs DEBUG10
    SUCCESS - 0 opening remote file \STS107\DEBUG10
    smb: \STS107\> Bus error (core dumped)

I didn't see anything in the archives back about 8 months on this.  I
turned up debugging to "-d 10".  Any clues?  Our security folks
*really* want the nifty logging Audit provides.

Thanks. 

Here's the audit sent to /var/log/messages:
