@RomanZ & @AlexanderD: where do we stand on the OP issue (segmentation fault on arch linux and Raspberry Pi 1 (with glibc > 2.23-1))?
are you making progress with the glibc team? staying on glibc 2.23 proved challenging are many other packages have now dependencies with more recent glibc versions...
I don't mean to sound rude, but 4 months (reported in this thread in june, but reports started in may on arch & aur forums) that arch linux RPi1 users cannot use their backup server/solution (see the irony?).
tried resiliio 2.4.0 & 2.4.1 (with arm (no hf) build): both still fail with segmentation fault on a simple rslsync --help
just for the record, the RPi 1 is a armhf board...
