This is an odd error, since the allocation failure is only for a very small
amount of memory. I'm guessing that something else has gone wrong earlier.
It may be that someone on the list has time to go through a lot of debugging,
but it's probably going to be up to you: can you do the usual
trouble-shooting? For example, does a non-QMMM calculation run? Does it
depend on which Hamiltonian you choose? Can you make a smaller test case?
It's also helpful to know if you have run lots of NEB calculations before, and
this is the first one that failed, or if you are new to all of this. It's
most helpful if you can show a run that works and one (as similar as possible)
