Seg Fault while connected to Windows (From Remmina)

[kobaz]

Describe the bug
I don't have a whole lot of detail. This just randomly happens while RDP-ing to various Windows systems. There doesn't appear to be any specific cause that triggers this.

To Reproduce
Steps to reproduce the behavior:

1. Connect to RDP server
2. Work as normal
3. Seg fault every few hours

Expected behavior
No seg faults!

Additional Info:
I captured this:

Hi, long backtrace, you experience some authentication/disconnects from time to time? (The log message in these traces is strange)

For further analysis, could you please attach the versions and connection settings?
Did you report this to the remmina folks too?

[antenore]

@akallabeth I asked myself to report this here as I was quite lost as well.
@kobaz uses the FreeRDP and Remmina packages that comes as default on debian 9.
One thing @mfvescovi noted, is that on bpo, the Remmina package has been loaded before the FreeRDP package.. Just wondering if there could be a difference in terms of symbols.

[akallabeth]

@antenore I think this is related to Remmina handling of rf_auto_reconnect, if you look at the stack trace 2 threads are calling it, which is definitely wrong...

[antenore]

Thanks @akallabeth I'll have a look

[antenore]

@kobaz do you open more than one connection at the same time on the same server?
We think that you have had two connections opened on the same server and you lost the connection.
In the future will fix this behavior, in the meanwhile, the only advice I can do is to try to open only one connection to the same server in Remimna when you don't have a reliable connection link.

[kobaz]

I didn't have more than a single connection per server..

Just caught another one today:

[akallabeth]

@kobaz better report this to remmina, this is a VNC connection stack trace...

[akallabeth]

closing as the issue is not freerdp but usage by remmina.
