Bug#328606: SEGFAULT on ssh login
Package: openssh-client
Version: 4.2p1-3
After the upgrade I did yesterday night, ssh segfault on login, after a
small pause:
mat@jericho:~$ ssh mbellett@annina.cs.unibo.it
Segmentation fault
I did recompile with -ggdb, gdb session with bt follows:
(gdb) run mbellett@annina.cs.unibo.it
Starting program: /home/mat/tmp/ssh/openssh-4.2p1/build-deb/ssh
mbellett@annina.cs.unibo.it
Program received signal SIGSEGV, Segmentation fault.

I'm running a Debian Unstable with a 2.6.12.5 kernel (for what it
matters). If more data from gdb debugging is needed, please be quite
detailed, I'm not much of an expert with it.
