** Description changed:
A user of us ran into this on his locally managed Ubuntu Natty i386
machine and I could reproduce it as follows:
auriga:~# mkdir /mnt/tmp
auriga:~# mount.cifs -o user=abe,rw,mand,uid=abe,gid=isg //unixdata/isg
/mnt/tmp

This is also reproducible on Debian Sid/Squeeze with gcc-4.1 through
gcc-4.5 (but not the default gcc-4.6) on i386. cifs-utils is at version
2:4.9-1 there. I'll file according bug reports there later, too, and
will reference them here.
(The mount options "mand" or "rw" aren't relevant, also happens with
"nomand" or "ro".)
This is not reproducible in the following cases:
* with Ubuntu Natty amd64 (so it seems to be architecture-dependent)
* with Ubuntu Maverick amd64 and gcc-4.4 (probably because of amd64, not
because of gcc-4.4)
* with Debian Sid i386 and gcc-4.6
* if I copy the files (e.g. with rsync -a) from the CIFS mounted file system
to /tmp and compile them there
* if I use NFS instead of a CIFS mount
* if I use sshfs instead of a CIFS mount (this is also the current workaround
we recommended our user as he can't do NFS mounts)
I couldn't check it on Lucid as mount.cifs bails out with "Mounting the
DFS root for domain not implemented yet". And I don't have a Maverick
box around.
I suspect the issue to be either in gcc-4.5 or cifs-utils, but I'm not
sure in which of them.
