Hi ports@, Since lang/ocaml was updated to 4.03.0, unison crashes every now and then with a segmentation fault on my amd64 machine (I use the no_x11 flavor of unison).
The backtrace (see below) suggests that this only happens when unison is used with a network connection. Indeed, I have not been able to reproduce it while synchronizing two local roots. I have been able to reproduce the problem both with SSH and the unison "socket method". To get a useful backtrace, I recompiled ocaml with the patch found below to enable the debugging symbols (compiling with DEBUG=-g didn't work). If I need to provide more information or if I can help in some other way, please let me know. Thanks, Caspar Schutijser ==> how to reproduce unison only seems to crash after quite some files have been transferred, so the number of changed files between the two unison roots need to be big. To make it easy to reproduce, I cloned a big git repository. Once the files have been transferred successfully, check out an old tag so lots of files change. Initialize the test environment: # useradd -m test # su - test $ ssh-keygen $ cat .ssh/id_rsa.pub >>.ssh/authorized_keys $ mkdir .unison $ echo "auto = true" >.unison/default.prf $ git clone https://github.com/postgres/postgres Run unison and observe how it segfaults: $ yes | unison postgres/ ssh://localhost//home/test/postgres.copy Once the entire repository has been transferred, check out an old postgres release to generate lots of changed files: $ cd postgres $ git checkout PG95-1_01 And then run unison again as described above. After that, if you want to go back to the master branch: $ cd postgres $ git checkout master And run unison again as described above. ==> backtrace $ egdb /usr/local/bin/unison /home/test/unison.core GNU gdb (GDB) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.
