[jira] [Comment Edited] (GUACAMOLE-1203) guacd, Release 1.2.0 segfaults in connection with RDP-Sessions

Hello [~mjumper],

I attached [^guacd_logs.tar.xz]. 
* {{guacd.log}}, log file of guacd. On 30. Oct the network connection was very instable and the bandwidth seemed to be pretty limited. Guacamole kicked me often out of the RDP-session. Just for the right log interpretation. 
* {{build.log, root.log}} are the relevant logs of the _Mock_ builder. I wrote a rpm.spec file making RPM-based packages and built it in a CentOS-7 change-root.
* Here, also an excerpt of the rpm.spec file with the {{BuildRequires}} (without ffmpeg): {code}
BuildRequires:  autoconf
BuildRequires:  automake
BuildRequires:  doxygen
BuildRequires:  libjpeg-devel
BuildRequires:  libtool
BuildRequires:  libwebsockets-devel
BuildRequires:  systemd-devel
BuildRequires:  pkgconfig(cairo)
BuildRequires:  pkgconfig(freerdp2)
BuildRequires:  pkgconfig(freerdp-client2)
BuildRequires:  pkgconfig(gnutls)
BuildRequires:  pkgconfig(libpng)

BuildRequires:  pkgconfig(pango)
BuildRequires:  pkgconfig(vorbis)
BuildRequires:  pkgconfig(winpr2)
{code}

Regarding the _freerdp_library, as said, the code where built with _Mock_. Inside the Mock change-root an CentOS-7 was installed and the code compiled and the binaries packtised into RPM-files. The hosts where guacd is running and where it was built are different but the _freerdp_ library is on production and built host the same:
* production host: {code}
[root@aguacate-srv-us1 redhat]# rpm -qa |grep freerdp
freerdp-libs-2.0.0-4.rc4.el7_8.x86_64{code}
* in CentOS-7 hange-root on build host, see {{root.log}}: {code}
*  grep freerdp root.log |less
