I tried again, but still segmentation fault:

nimnul at 217 (~) > sftp localhost
Connecting to localhost...
The authenticity of host 'localhost (127.0.0.1)' can't be
established.
DSA key fingerprint is d2:4c:d9:fa:b6:d8:92:20:ec:a4:7f:35:19:15:a9:d6.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'localhost' (DSA) to the list of known hosts.
Password:
sftp> put aaa.bbb
Segmentation fault (core dumped)

I tried it on different FreeBSD machines, with the same result

Is this compiled by you?  Or are you using ports or FreeBSD in-tree OpenSSH 
version?  I can't find anyone that can mimic this.

Can you get a gdb trace of where it is failing?

You need to give it the binary as well as the core to get meaningful results, ie

$ gdb /path/to/sftp sftp.core
(gdb) bt

I had to upgrade from in-tree OpenSSH to newer OpenSSH. I updated ports using 
cvsup, compiled ssh from ports and deleted files from old one using rm. Did I 
make something wrong?

FreeBSD glob has had problems in the past - I suspect that is the problem.

I would recommend using the in-tree OpenSSH for FreeBSD. Please report if that
breaks.
