Could it be an issue with running out of memory? Do the system logs have
anything interesting in them around the time it goes haywire?

When it's dumping contents to the screen, it's not stderr, but stdout. I
collected 224Gb of logs tonight before the backup aborted. (Good thing this
is a backup host with storage capacity…)
The point where it started dumping content during that first run was here:

I tried excluding the entire directory to see if the problem still
occurred, this time on a different location perhaps, and it did… so it's
not any specific file in that directory.
The second time, it started acting up here:
Can't open /var/lib/backuppc/pc/host.hypervisor.srv.1024.lu/858/f%2f for
MD4 check (err=-3, .)
.: md4 doesn't match: will retry in phase 1; file removed
Must redo 0 (.)\n

So I don't know where to head on from here.
