Package: klibc-utils
Version: 2.0.12-1
Severity: normal
Hi,
I observed segfaults in armhf architecture when executing any of the
binaries /usr/lib/klibc/bin/{fstype, ls, cat, ...}, same is not seen in
amd64 and arm64 architectures.
This issue originally occurred when I am updating initramfs using
command `update-initramfs -u` which internally [1] uses klibc binary
`/usr/lib/klibc/bin/fstype` to check the fstype, it doesn't stop
creating initramfs but it creates core dumps in the rootfs and that
makes our images non-reproducible.
Follow below steps to reproduce this issue
```
$ sudo debootstrap --arch=arm bookworm arm-bookworm-rootfs/
http://deb.debian.org/debian/
$ sudo chroot arm-bookworm/ apt-update && apt install -y klibc-utils
$ sudo chroot arm-bookworm/ /usr/lib/klibc/bin/fstype --help
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault
```
Expectation:
It should not generate core dumps
Kindly suggest us what is going wrong where all the binaries are generating
core dumps in armhf architecture?
