webrtcbin segmentation fault

[Lusine]

Hi Folks,
I'm facing to an issue with webrtcbin. Its' examples from here produce
segmentation fault on my machine:
https://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/tests/examples/webrtc/webrtc.c

I have the following version of gstreamer:
GStreamer 1.14.5

Also installed this:
sudo apt install gstreamer1.0-nice

And my machine is:
Ubuntu 18.04.5 LTS , which I run from WSL

This is how I compile the code:
gcc -Wall webrtc.c -o webrtc -lgstwebrtc-1.0 $(pkg-config --cflags --libs
gstreamer-plugins-good-1.0 gstreamer-plugins-bad-1.0 ) -lgstsdp-1.0

And executing it pruduces segmentation fault:
export GST_DEBUG="*:4"
./webrtc

...
