Bug Description

/usr/sbin/sshd writes on start:
Segmentation fault

After system start in dmesg I can see:
Jan 6 23:42:20 hostname kernel: [ 116.264508] sshd[4029]: segfault at 8be2f2d8 eip b7ea5196 esp bfec5f70 error 6

The same problem with ntpdate.
/usr/sbin/ntpdate writes on start:
Segmentation fault

In dmesg:
Jan 6 23:48:21 hostname kernel: [ 477.322983] ntpdate[4219]: segfault at 8bf07020 eip b7f14196 esp bfbd0f64 error 6

I installed gdb and saw in backtrace, that problem is in /lib/ld-linux.so.2.
/lib/ld-linux.so.2 is in libc6 package, I installed libc6-dbg package and get this using gdb:
Program received signal SIGSEGV, Segmentation fault.
0xb7ef0196 in _dl_map_object_from_fd () from /lib/ld-linux.so.2
