I assume this is on Debian/unstable?  I can't directly replicate this on
my 24core (Debian/stretch) or 16core(Ubuntu/xenial) machines.  I'll
setup a chroot soon, but since you've said -j64 is fine there too I
suspect you have more cores than I.  This may be something you have to
bisect for us if I can't replicate it myself.  Can you confirm how many
cores you have?  I might be able to spin something up in Google compute.
Thanks!
