Hi @philippe44

i have just updated the synology package for AirConnect release 0.2.26.0 with your newest binaries.
I am using the airupnp and aircast binaries for arch x86-64 for testing.

If i start the package with a high-privileged user (such as root) i can start airupnp without any problems and it is running fine.
If i am trying to start airupnp with a low-privileged user, airupnp crashes directly after the start without an error but it generates a core dump and is throwing a seg faults in the messages log.
For the synology package i need to start the binaries as a low-privileged user.

2020-05-27T20:02:27+02:00 xx kernel: [76992.162360] airupnp[19007]: segfault at 0 ip 00007f5a8cb314bd sp 00007f5a87b69db0 error 4 in libc-2.20-2014.11.so[7f5a8cac7000+19b000]
2020-05-27T20:02:27+02:00 xx coredump: Process airupnp[18995] dumped core on signal [11].

I have used the same scripts, build steps, same low-privileged user etc. as of version 0.2.25.0. So it should be no problem with the synology package.
Version 0.2.25.0 is working fine for the moment.

Startup commands:

i am not using the config file in my tests (no file exists)

/volume1/@appstore/AirConnect/airupnp -b 192.168.1.x:49154 -l 1000:2000 -x "/volume1/@appstore/AirConnect/config.xml" -z -f "/var/log/airconnect.log" -d all=info
