I have an Arch guest in VirtualBox running on an Arch server. I installed virtualbox-bin 1-34-2 from AUR with 5.18 patch and the install on the host went fine.
I access the guest headless using rdesktop over the LAN. (have done so for years). Doing a full system update from 5.17.7 to 5.18.6 (about 25 days of updates) on guest.
Pacman segfaulted leaving post transaction hooks unrun. I reinstalled the kernel and systemd to force the initrd to be made so the guest is bootable.
Perhaps you already did so, but did you check the health of the host (filesystem & RAM)? You mentioned a couple of errors, like segfaults and decompression errors. Especially that last one sounds like a corruption somewhere.... As these errors happened in a VM, is it possible to copy the virtual harddisk to another host (hardware) and trying again? To be honest: the RAM is my first suspect, but it could very well be an io error on the underlying host. I really doubt that it's caused by the installed software. Mvg, Guus Snijders
