--- Comment #59 from Jürgen Reuter <juergen.reuter at desy dot de> --- Yes, to me this looks also like an independent problem, and it appears to me like a sort of race condition. I also just restarted the bootstrap (without a parallel make). Now I have to do some theoretical physics, will know more tonight.
