Hi,

I can reproduce the problem. The root cause is not, that imudp is loaded twice,
but that you have multiple instances of $UDPServerRun

So this:
$ModLoad imudp
$UDPServerRun 514
$UDPServerRun 515 (doesn't really matter, what port you choose)

will also cause a segfault

I can verify this for both 3.18.4 and 3.20.5 and 3.22.0 (haven't tested master 
yet).

Rainer, are you able to reproduce the problem with this information?

Cheers,
Michael
