if i add streaming plugin permanent info, then janus segment fault

[kimilpyoung]

i used api and send
{ request: 'create',
type: 'rtp',
id: 33,
description: 'domain',
audio: true,
video: true,
audioport: 9000,
audiopt: 111,
audiortpmap: 'opus',
videoport: 5800,
videopt: 96,
videortpmap: 'VP8',
permanent: true }
to my janus server

but janus is down with "Saving mountpoint 33 permanently in config file
Starting streaming relay thread
segmentation fault (core dumped)"

permenent : false is not error, but only true occured error

Did I put anything wrong?

i show this message debugging core file

[lminiero]

As it's written pretty much everywhere, PLEASE DO NOT write dumps inline! They mess up references to old issues, and make issues unreadable. I've edited the formattation for you, I'll simply close the issue next time.

[kimilpyoung]

Sorry for my mistake.. I'll be careful next time.

So.. you know anything about the cause?

Is it just a bug? Or is it my server problem?

[ghost]

I have the same issue. Whenever I try to create a mountpoint permanently to the configuration, I get segmentation fault. Happens locally as well as on my server.

Backtrace
address sanitizer

It's on Ubuntu 16.04 (locally) and 18.04 (server), it's compiled with openssl 1.1.0g.

[lminiero]

Make sure you try with master, as I recently fixed an issue in the configuration management code in the core.

[ghost]

It works now.

My mistake was that I hadn't pulled from master the last few weeks.

[lminiero]

Good to know that's fixed! I'll probably have to tag a new version soon, if 0.6.0 has this issue. Closing then.
