             Summary: Son of immediate double-free upon connecting to Windows RDP
                 Key: GUACAMOLE-1259
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1259
             Project: Guacamole
          Issue Type: Improvement
          Components: RDP
    Affects Versions: 1.3.0
            Reporter: Mike Jumper


From GUACAMOLE-1241:

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.

This is still happening when building against FreeRDP 2.0.0-rc4, not because things are incorrectly detected at build time, but because the {{config.h}} header containing the macro resulting from that detection is not included in the relevant file. The call to {{Stream_Free()}} therefore always occurs, even if FreeRDP was detected as doing this automatically.
