Nick Couchman commented on GUACAMOLE-1903: ------------------------------------------ [~svogl]: A couple of follow-up questions for you: * In the output you sent, I'm not actually seeing the double-free error or any analysis that shows where it is? Can you provide any further detail on that? * When you do the upgrade from Guacamole 1.4 to 1.5.x, are you making any other changes - like host O/S (or Docker container) upgrade, libvncclient, etc.? * Can you provide details on the platform you're using - Linux distro/version, etc.? > guacd 1.5.4/master double free issue > ------------------------------------ > > Key: GUACAMOLE-1903 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-1903 > Project: Guacamole > Issue Type: Bug > Components: guacamole-server, guacd > Affects Versions: 1.5.4 > Reporter: Simon Vogl > Priority: Major > Attachments: drd.log > > > Hi all, > we have a running 1.4 installation that serves vnc connections (only). I am > trying to upgrade to a recent code basis as we want to add some features > (alt-f4 etc on the OSD). > I installed client and server versions 1.5.4 on a test machine and it works > only for some of our client boxes (ones in our office,p.ex.) but guacd dies > for other connections (at a remote site behind a firewall) with a 'double > free' error. Guacd seemingly dies when cursor movements happen on the web > client, and I saw it happen consistently when the mouse enters / leaves the > rendered remote display in the browser window. > I ran guacd with the valgrind drd tool > valgrind --tool=drd --trace-fork-join=yes /usr/local/sbin/guacd-1.5.4a -f -L > trace -b 127.0.0.1 -l 4822 -p /tmp/guacd.pid > and captured the state in the attachmed drd.log when guacd died away. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
