I build from a fresh git checkout.

I just tried again, I can reproduce it in a pbulk (basically, building
lots of programs in a chroot), but not when manually building in the
same environment. Weird, I don't understand this. It's always after
printing the "20000" line for that file.

Do you have any ideas what could cause this?
