It is one of those trivial cases.  If you add say -crit 1.e-7 to the command
line the problem will go away.  More serious is why it is there. The
gradient at the first function evaluation is already smaller than the 
convergence value so it never gets into the minimization routine so the
variable that hold the best log-likelihood value never gets set. That 
should be fixed.
