Public bug reported:
Trying to run a bare chroot with no additional bind mounts fails on git
master (8ffa52c20d5693d454f65f2024a1494edfea65d4) with:
root@nofan:~/qemu> chroot /local_scratch/sid-m68k-sbuild/
qemu-m68k-static: /root/qemu/linux-user/elfload.c:2315: pgb_reserved_va: Assertion `guest_base != 0' failed.
Aborted
root@nofan:~/qemu>
The problem can be worked around by bind-mounting /proc from the host
system into the target chroot:
root@nofan:~/qemu> mount -o bind /proc/ /local_scratch/sid-m68k-sbuild/proc/
root@nofan:~/qemu> chroot /local_scratch/sid-m68k-sbuild/
bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
(sid-m68k-sbuild)root@nofan:/#
Host system is an up-to-date Debian unstable (2020-07-23).
I have not been able to bisect the issue yet since there is another
annoying linux-user bug (virtual memory exhaustion) that was somewhere
introduced and fixed between v5.0.0 and HEAD and overshadows the
original Assertion failure bug.

Could you point me to a tar.gz with your rootfs?

For the record, reproducing this problem requires root, thus
trying to reproduce it outside of a chroot is non-obvious.
