segfault after last patch...

[dl1bz]

After your last patch (BSD updates) I got a segfault on my debian buster at Pi if I start DMRGateway. Compiling is ok. Segfault is shown if the DMRGateway start the connection to the networks. Disable some networks has no effect, segfault in all cases.

If you could compile it for debug, and run it under gdb, that would be very interesting. That would show you (and me) what line it fails at.
