Comment 3 for bug 1897854

I'm also running into this trying to set up a pbuilder environment:

$ pbuilder-dist sid armhf create
...
I: Running command: chroot /var/cache/pbuilder/build/430992 /debootstrap/debootstrap --second-stage
qemu-arm-static: /build/qemu-W3R0Rj/qemu-5.0/linux-user/elfload.c:2317: pgb_reserved_va: Assertion `guest_base != 0' failed.
Aborted (core dumped)

This appears to have been fixed upstream [1, 2] in qemu 5.1, which has been in Debian unstable since August [3], but hasn't been merged into Ubuntu yet.
