I agree. I couldn't reproduce my 4.3-stable box.
The version of that ssh is
SSH Version OpenSSH_2.3.0 green@FreeBSD.org 20010321.
But, I could reproduced on -current which was build on 2001/01/12.
And the version of that ssh is OpenSSH_2.3.0.
On the other hand, I had an another sshd.core on my 4.2-stable box
which is:
4.2-STABLE FreeBSD 4.2-STABLE #0: Thu Mar 1 12:26:02 JST 2001
The following is the backtraces:
---
This GDB was configured as "i386-unknown-freebsd"...
(no debugging symbols found)...
Core was generated by `sshd'.
Program terminated with signal 11, Segmentation fault.
Reading symbols from /usr/lib/libopie.so.2...(no debugging symbols found)...
done.
(snip)
Reading symbols from /usr/libexec/ld-elf.so.1...(no debugging symbols found)...
done.
#0 0x281791c8 in login_getpwclass () from /usr/lib/libutil.so.3
(gdb) where
#0 0x281791c8 in login_getpwclass () from /usr/lib/libutil.so.3
#1 0x80532e8 in getsockname ()
#2 0x805a9ef in getsockname ()
#3 0x8052fd0 in getsockname ()
#4 0x804d81d in getsockname ()
#5 0x804be95 in getsockname ()
---
In this case, sshd caught signal 11. But the reason why sshd dumped
core on that box isn't clear to me. I can, however, reproduce it.
In order to get sshd.core, I only have to type
% slogin that_host -l nonexistent_user_name
The version of ssh is
SSH Version OpenSSH_2.3.0, protocol versions 1.5/2.0.
