Thanks Dr. Marques. You were right. The limit on stacksize was set too
low. After increasing the limit, I can run much larger (finer-grid,
that is) models now.
Thank you very much.

It really looks like that there is not enough memory. The symptoms are
clear. Note that the LCAO takes a lot of memory. That's why you can run
without LCAO for smaller spacings. It is strange, though, as the benzene
molecule is quite small. I guess that you either are running in a
machine with very little memory, or you have a funny compiler that needs
some funny flags to allow the use of more memory. It is possible also
that you have very stringer settings in you machine (type limit or
ulimit, depending on your shell).
