Title:
qemu-aarch64-static segfaults running ldconfig.real (amd64 host)
Status in QEMU:
New
Status in qemu package in Ubuntu:
Triaged
Bug description:
This affects the qemu-user-static 1:8.2.2+ds-0ubuntu1 package on
Ubuntu 24.04, running on a amd64 host.
When running docker containers with Ubuntu 22.04 in them, emulating
arm64 with qemu-aarch64-static, invocations of ldconfig (actually
ldconfig.real) segfault. For example:
$ docker run -ti --platform linux/arm64/v8 ubuntu:22.04
root@8861ff640a1c:/# /sbin/ldconfig.real
Segmentation fault
If you copy the ldconfig.real binary to the host, and run it directly
via qemu-aarch64-static:
$ gdb --args qemu-aarch64-static ./ldconfig.real

It looks like this is a known qemu regression after v8.1.1:

Downgrading the package to qemu-user-
static_8.0.4+dfsg-1ubuntu3_amd64.deb fixes the segfault.
