1. Make sure you have the necessary "deb-src" entries in your sources.list:

# binary default
deb http://ftp.ports.debian.org/debian-ports/ unstable main
deb http://incoming.ports.debian.org/buildd/ unstable main
deb http://ftp.ports.debian.org/debian-ports/ unreleased main

# source
deb-src http://ftp.debian.org/debian/ unstable main
deb-src http://incoming.debian.org/debian-buildd/ buildd-unstable main

2. Run "apt update"

3. apt install devscripts && apt build-dep firebird3.0

4. dget -u http://deb.debian.org/debian/pool/main/f/firebird3.0/firebird3.0_3.0.2.32703.ds4-1.dsc

5. cd firebird3.0-3.0.2.32703.ds4/

6. ./debian/rules binary-arch

It should hang at some point when running the compiled binary on Aranym
or qemu-system. On qemu-user, it will just crash but for other reasons.

Although I didn't test it with qemu-system, I am very confident it should
hang the same way as on Aranym. The qemu-user crash is related to the
broken atomics in qemu-user.
