glibc 2.14-4 eats my data (Re: F15 ext3, eCryptfs + samba = data corruption (Re: F15 "Error mounting eCryptfs: [-5] Input/output error" on different disks))

Hi,

When I did a glibc downgrade to 2.13.90-9 eCryptfs mount problem no
longer appears, also there is no data corruption problem. Glibc
changes somehow breaks eCryptfs and probably also samba.
