[Dock-fans] Segmentation fault on running docking

Having solved empirically, whitout external help, the problem (posted on last
week-end) of running grid when residue HOH is present within the pore, I am now
faced by segfault in running rigid docking. That occurs both on parallel and
serial run. It also occurs with previous files for the protein without HOH,
where both rigid and flex run OK on mpirun -np 4. Thus, it seems that there is
now something wrong with dock6 and I don't understand what.
Before these unsuccessful attempts, I had
(1) Unsuccessfully tried to recompile Antechamber with new respgen.c (on
Amber9), which did not affect previous compilation.
(2) Carried out "apt-get update" to Debian Linux amd64 etch (i.e., stable)
without taking notice of the little that was affected.
mpirun -np 4 -i rigid.in -o rigid.out
the process halted (rigid_scored.mol2 0 bytes) because

I tried also flex with the protein endowed of HOH
mpirun -np 4 -i anchor_and_grow.in -o anchor_and_grow.out 2>&1 | tee errors.out
with an even more complex of libraries and mpi problems (see please attachment.
Parallel dock had so far run correctly. DOCK6.1 had been compiled with:
./configure gnu parallel
I have now unsuccessfully deselected $AMBERHOME in my .bashrc, as expected
because it should be only relevant to running amber_score. I did not change
otherwise my .bashrc, where
PATH=$PATH:$DOCK_HOME/bib; export DOCK_HOME PATH
I have now tried the test
make 2>&1 | tee test_parallel.out
which passed OK.
Also on serial trial, segfault:
dock6 -i rigid.in -o rigid out
