*** Error code 255

There's no test summary report, just this error message. It's impossible to tell how many tests succeed, and how many tests fail in total.

Version: 0.17.9 FreeBSD 13.1

Is it a random failure or does it happen consistently?

Indeed, for now test are simply run it order and when something fails it stops. I opened issue https://github.com/paullouisageneau/libdatachannel/issues/683 to introduce a proper test framework.

[yurivict]

This is a spurious error.

[paullouisageneau]

OK, I think I've seen the issue happening once or twice with the CI, so it's probably not FreeBSD-specific. Thank you for reporting, I'll investigate.
