Public bug reported:
Binary package hint: smbfs
We have samba (3.0.22-1ubuntu3.3 on dapper) configured as PDC in our domain .
When I try to mount any of the cifs shares on the client (feisty samba
3.0.24-2ubuntu1.2) using command like:
mount -t cifs //fileserver/share /some/where -o user=name
i got this:
*** glibc detected *** /sbin/mount.cifs: free(): invalid pointer: 0x0805080a ***

Weird thing is that after this command share is being mounted and I can
access it, so this error is not so fatal. Nonetheless we using pam_mount
in our environment, and IMHO this error causes pam_mount to be unable to
unmount shares on logout. I can supply more informations if needed.
