Mike Jumper commented on GUACAMOLE-1241:
----------------------------------------
I notice the following is logged during the Docker image build:
{code:none}
checking whether FreeRDP appears to be a development version... yes
configure: WARNING:
--------------------------------------------
You are building against a development version of FreeRDP. Non-release
versions of FreeRDP may have differences in behavior that are impossible to
check for at build time. This may result in memory leaks or other strange
behavior.
*** PLEASE USE A RELEASED VERSION OF FREERDP IF POSSIBLE ***
--------------------------------------------
{code}
That might be related.

> Project: Guacamole
> Issue Type: Bug
> Components: RDP

> Reporter: Mike Jumper
> Assignee: Mike Jumper

> Fix For: 1.3.0
>
>
> Regression testing against {{staging/1.3.0}} using the Docker image, I am
> seeing an immediate disconnect due to a double-free when attempting to
> connect to Windows RDP:
> {code:none}
> ...
> guacd[24698]: INFO: Loading keymap "base"
> guacd[24698]: INFO: Loading keymap "en-us-qwerty"
> guacd[24698]: INFO: Connected to RDPDR 1.13 as client 0x0005
> free(): double free detected in tcache 2
> guacd[6]: INFO: Connection "$e6955582-c6f2-4912-a4bd-a3ffee002cd1"
> removed.
> {code}
> With there being a few memory-related RDP changes in the upcoming release
> (and with no such issues in 1.2.0), I suspect this is a regression.
