Even with PARALLEL_MAKE and BB_NUMBER_THREADS commented out in my local.conf
I can reproduce the failure within a few minutes using the following loop.

while :; do
	./bitbake.sh -b openembedded/recipes/mozilla/nspr_4.7.1.bb -c clean
	./bitbake.sh -b openembedded/recipes/mozilla/nspr_4.7.1.bb -c compile || break
done
