The source might be this procedure:

   group_size=max(1,int(n_total_states/500))                            
   do i1=1,n_total_states,group_size                                    
     call ef2nel(Tel,E_sorted(i1),n_of_el_from_zero(1),'both ')         
     if (n_of_el_from_zero(1)<-nel_diff_zero) i_Ef(1)=i1                
     if (n_of_el_from_zero(1)> nel_diff_zero) then                      
       i_Ef(2)=i1                                                       
       exit                                                             
     endif                                                              
   enddo                                                                

since changing the total number of bands from 600 to 1000 group size changes from 1 to 2

I tried and in my case the code works just fine. I suspect the issue was in the compilation or in something else. I close this.
