[jira] [Created] (GUACAMOLE-950) segfault in guacd

Toby created GUACAMOLE-950:
------------------------------

             Summary: 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
         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.
