@stefan-haberland sorry I missed this issue before...

I was able to reproduce it by generating BLS snippets with the following script:

#!/bin/bash

for i in {0..9}
do
  cat << EOF > /boot/loader/entries/vmlinuz-${i}.conf
title Red Hat Enterprise Linux (vmlinuz-${i}) 8.0
version $(uname -r)
linux /boot/vmlinuz-$(uname -r)
initrd /boot/initramfs-$(uname -r).img
options $(cat /proc/cmdline)
EOF
done

And then zipl segfaults:

# zipl --dry-run

Using BLS config file '/boot/loader/entries/vmlinuz-1.conf'
Using BLS config file '/boot/loader/entries/vmlinuz-0.conf'

Aborted (core dumped)

I'll investigate what could be causing this.
