> segfault in guacd
> ------------------
>
> Key: GUACAMOLE-950
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-950
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole-server
> Affects Versions: 1.1.0
> Environment: Guacamole 1.1.0 under Tomcat8 on Ubuntu 18.04, running
> as virtual machine
> Reporter: Toby
> Priority: Minor
> Attachments: trace_connected.txt, trace_segfault.txt
>
>
> Upgraded from 1.0.0 on Ubuntu 16.04 to 1.1.0 on Ubuntu 18.04. Moved from
> Tomcat7 to Tomcat8. Config is largely unchanged.
> Two Windows 10 Enterprise destinations and a third is 2012R2. One of the two
> Windows 10 will cause guacd to segfault on connection. 2012R2 works fine. I
> see a mouse pointer in the upper left very briefly and then I get
> home/reconnect/logout. I have pared the config down to just domain,
> username, password, NLA security, ignore-cert directives for all three
> destinations.
> Uploaded syslog traces, one of a normal connect to the other windows 10
> device, one as the segmentation fault I get when connecting to the other.
> Have also tried rebuilding without webp and websockets to no effect.
> I'm happy to build one for gdb and get a core, but I'll need a little help
> doing that.
