Hello everyone,

I updated 15.5 to 15.6 some days ago after that I noticed that ssh connection
doesnt work anymore.

I as I found out, as long as  GSSAPIKeyExchange option is on the ssh client
crashes.

Versions on System:
opnessh 9.6p1 - 150600.6.9.1
openssh-clients 9.6p1 - 150600.6.9.1

Workaround:
If you turn off GSSAPIKeyExchange in /etc/ssh/ssh_config (or else you turned it
on) everything works fine (even with Kerberos)
