Segmentation fault on RPI Zero W - Raspberry Pi OS 20-08-20

[nordseele]

Environment :

Device: Raspberry PI Zero W (Armv6)
OS: Raspberry Pi OS 20-08-20 (same errors with the previous OS).

I tried to install Serialosc on a RPI Zero W following the instructions found on this page https://monome.org/docs/serialosc/raspbian/

Installing with the package fails so I tried to compile from source. Here are the details.

Install with the package:

• The service doesn't seem to start automatically.

systemctl status serialosc.service
   serialosc.service
   Loaded: loaded (/lib/systemd/system/serialosc.service; disabled; vendor preset: enabled)
   Active: inactive (dead)

• Running serialoscd manually returns a "Segmentation fault".

Compiling from source:

Serialosc won't compile easily.
./waf returns a lot of warnings/errors. Here's the full output of ./waf -v

Changing line 257 of serialosc/wscript to
conf.env.append_unique("CFLAGS", ["-std=c99", "-Wall", "-Wno-error"])
Serialosc will compile but serialoscd is not found

But after a reboot running serialoscd is working this time...
