Re: svn segfault when using svn+ssh schema

I'm getting segfaults from svn but only when using ssh as the schema.
The following three commands are all accessing the same server, the name
of which has been changed to protect the guilty.

SamEdge@thor ~
$ ssh
( success ( 2 2 ( ) ( edit-pipeline svndiff1 absent-entries
commit-revprops depth log-revprops atomic-revprops partial-replay
inherited-props ephemeral-txnprops file-revs-reverse ) ) )
SamEdge@thor ~
$ svn ls svn+ssh://
Segmentation fault (core dumped)

SamEdge@thor ~
$ svn ls

SamEdge@thor ~

Access using TortoiseSVN using either schema is working fine, as is
access from Linux svn.

The server is Ubuntu 14.04.5 LTS with package subversion
1.8.8-1ubuntu3.2, openssh-server 1:6.6p1-2ubuntu2.8 and openssl

The secure shell access is using public key authentication.

I've attached cygcheck & the segfault stackdump.

I'm at a loss. Any ideas?

Sorry, I have no further ideas. svn+ssh is working fine for me here using both Cygwin and Debian as the server. Debian is running Subversion 1.8.10.

I personally lack the technical skills to decode the stack trace. Maybe someone else can. Alternatively, you could theoretically download the subversion debug package and reproduce the error in gdb to get a backtrace. Again, my C/gdb skills are rusty, so I can't provide any details about how to do that.
