I missed the question. Probably hit the spam bucket for some reason.
I am able to reproduce it with more recent versions as well.
The most recent one I have around is 5.4.0-0.bpo.2-amd64
Still reproducible 100% - just tested it.
It is trivial to reproduce if anyone actually bothers to do so. Just
grab a big enough tree where make runs truly in parallel - openwrt is
best, but even the Linux kernel does the job.
Mount it via nfs4 from another server (it will work even locally, but
takes longer to reproduce - may take a whole afternoon)
Run while make -j 12 clean && make -j 12 ; do true ; done
Leave it to run. On 6 cores/12 threads it takes 2-3 builds of openwrt or
~ 5-8 linux kernel builds to blow up. More cores - faster. Less cores
slower.
I sent it to the mailing list too, but nobody could be bothered to even
ask any questions.
