>Synopsis: ssh(1) dumps core when ControlPath used in ~/.ssh/config
>Category: system
>Environment:
System : OpenBSD 6.0
Details : OpenBSD 6.0-beta (GENERIC.MP) #2280: Mon Jul 11 05:20:56
MDT 2016
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
% cat ~/.ssh/config
Host *
ControlMaster auto
ControlPath ~/.ssh/control-%r@%h:%p
ControlPersist 1
The above ~/.ssh/config file has been working fine for years - until
a couple of days ago, that is (i.e. GENERIC.MP#2268 amd64 worked fine).
The below issues are present regardless of whether a password- or a key-
based authentication is being used.
Now running ssh(1) dumps the core:
% gdb -q ssh ssh.core
(no debugging symbols found)
Core was generated by `ssh'.
Program terminated with signal 6, Aborted.
(no debugging symbols found)

>How-To-Repeat:
Use the above ssh_config(5) file and try connecting to a remote system.
>Fix:
Older snapshots, i.e. GENERIC.MP#2268 amd64, worked fine.
I.e. commenting the below line, or removing all of the Control* keywords
makes ssh(1) work again:
# ControlPath ~/.ssh/control-%r@%h:%p
