Package: liblzma5
Version: 5.8.1-2
Severity: serious
Hi,
see below for the stacktrace. This nonsense started a few days ago. The
system is perfectly stable otherwise, so I don't think this is a
hardware issue.
So I was trying to compile an upstream Linux kernel. Command, which has
been working for years, is:
$ nice -n20 make bindeb-pkg -j14 KCFLAGS='-march=x86-64-v3 -mtune=znver3'
And now it keeps segfaulting, like:
STRIP
debian/linux-image-6.18.0/lib/modules/6.18.0/kernel/virt/lib/irqbypass.ko
DEPMOD debian/linux-image-6.18.0/lib/modules/6.18.0
dpkg-deb: Paket »linux-image-6.18.0« wird in
»../linux-image-6.18.0_6.18.0-84_amd64.deb« gebaut.
dh_builddeb: error: dpkg-deb --root-owner-group --build
debian/linux-image-6.18.0 .. died with signal 13
dh_builddeb: error: Aborting due to earlier error
make[3]: *** [debian/rules:66: binary-image] Fehler 2
And why? The stacktrace from coredumpctl reveals:

But why?
Okay, then I wanted to install one of my existing kernel-image DEBs. And then
initramfs build also started crashing.
But why? The common factor here was, again, liblzma5!
So I have changed the compression type of initramfs to zstd and now it works...
somehow. Still not explaining what is happening with liblzma5 here.
Best regards,
Eduard.
