Any idea, what's going on? Why can't FreeBSD's restore read FreeBSD's
dump's output?

No big difference:
dump a0f - /old | restore -rf -

Looks like a junk value somewhere... Unitialized variable or some such.
can you try splitting it in 2, ie no pipe?
dump a0f some.file /old (or dump 0f - /old | gzip -c > file.dump.gz)
restore rf some.file

Well, the first part (the dump) runs almost to the completion, but hangs
at the very end for some reason:

The timestamp on the output file is, indeed, 10:38 and the dumping
process is hanging ever since then (over 90 minutes already).
