You're dividing by zero in pathd8/mpl.c:

      subtree_var[i] =  n->child[i]->var + n->edge_len[i];
      ...
      p_bar_numerator += subtree_est[i]/subtree_var[i];

because the terminal node 'Frog' has var and edge_len
both equal to zero.

Possibly gcc/linux reacts differently to division by zero?
