Segfault when using unison 2.32.52 in sid

[nathael <nathael.pajani@nathael.net>]

Hi,

I have a segfault when using unison2.32.52, both text and GTK versions.

$ dpkg -l |grep unison
ii  unison2.32.52        2.32.52-7+b1  amd64  [...]
ii  unison2.32.52-gtk    2.32.52-7+b1  amd64  [...]

$ cat /etc/debian_version
stretch/sid


Tried to re-compile from sources (apt-get source unison2.32.52), but compiled version also
segfaults.

Here is a gdb backtrace

(gdb) run

Got the segfault whether running with no profilename or with an existing profilename


drizzt@drzwork:/tmp/unison/unison2.32.52-2.32.52$ ./unison dmadmin
ð}ppErreur de segmentation


When using the GTK version, the crash happens after choosing the profile when using
unison-gtk and even after entering the password for remote hosts with no SSH key (all my
profiles are for remote hosts over SSH).
$ unison-gtk
@zXzErreur de segmentation



Also tired the Unison version from the git repository but did not find how to build for
version 2.32 instead of version 2.48.
(git clone git://git.debian.org/git/pkg-ocaml-maint/packages/unison.git)



Any clue ? (Other than migrating the repositories to 2.48 and hope for 2.48 to be working ?)

Thanks :)
