I have been building current twice daily for a while and didn't notice
this regression but I do have the space after "-j"
#!/bin/sh
make -j 16 buildworld > /logs/bw.$$ 2>&1 && \
make -j 8 kernel KERNCONF=GENERIC > /logs/bk.$$ 2>&1 && \
sync && reboot
I grepped all my logs across 3 servers and did not see a single instance
of [_cleanworldtmp] Error code ... in any of the logs. What was the hash
of the build you were on there, I can try to reproduce it quickly (but it
might only trigger with your builddir state I guess)
