Hi. For the record: I get a similar failure on amd64 when using "make --shuffle".

I have not announced this anywhere yet, but you can find a build log
for cod-tools here in the build-logs directory:

https://people.debian.org/~sanvila/make-shuffle/

So, because it happens easily when using make --shuffle, I believe it's a Makefile bug.

Thanks.
