Possible bug with dihedrals in "molecule" command?

Dear all,
I am trying to load molecules into a simulation via the "molecule" command in lammps-1feb14. I think I wrote everything according to the documentation (see example below for an 8-atom linear chain).
Nevertheless i get errors before the start of the simulations, which I believe are related to the dihedrals and how they are read. In fact removing that section clears all possible errors.

The dihedrals of my molecule are defined as

Dihedrals

1 1 4 3 2 1
2 1 5 4 3 2
3 1 6 5 4 3
4 1 7 6 5 4
5 1 5 6 7 8

Writing the first line as
1 1 1 2 3 4
thus with the atom IDs reversed but still ordered linearly gives a "segmentation fault" error. The same occurs if I write the last line as
5 1 8 7 6 5

Moreover, in another simulation I got the following error

LAMMPS (1 Feb 2014)
Created orthogonal box = (0 0 0) to (40 40 100)
   1 by 1 by 1 MPI processor grid
Created 4744 atoms
4744 atoms in group fluid

Setting up run ...
ERROR on proc 0: Dihedral atoms 4 3 2 0 missing on proc 0 at step 0 (../neigh_bond.cpp:540)

or with more processors

ERROR on proc 0: Dihedral atoms 4132 4131 4130 4128 missing on proc 0 at step 0 (../neigh_bond.cpp:540)

In my opinion the listed atoms be 4 3 2 1 (instead of 4 3 2 0) or 4132 4131 4130 4129 (instead of 4132 4131 4130 4128). Perhaps there is an issue with how the neighbors lists for dihedrals are generated in the molecule command.

Any ideas about this issue?

Thank you in advance and best regards,

I believe this has been fixed in a more
recent version.

Dear Steve,

thanks for your answer. I found the bug fix in the 26.02.2014 update, and compiling the latest development version solved the problem.

Best regards

Daniele
