Using interpipe elements in GStreamer 1.19

[Igor Petetskih]

Hi. I am trying to create pipeline with switching source. Now I am trying
to use interpipe* elements (
https://developer.ridgerun.com/wiki/index.php?title=GstInterpipe_-_Simple_Examples
)

I created the simple program with 2 pipelines (source and sink) and this
program throws and SIGSEGV.

Can someone provide me a some advice, how to find out where is the issue?
Or provide a simple working example of using these interpipe* elements
withoud GstreamerDaemon (all examples from official documentations related
on this daemon)

my sample program: https://pastebin.com/QNSBdGfT
error log from program:  https://pastebin.com/aRHcahCA

Very thanks,

Igor.
