I am not sure how I could trace this down. I'm running tleap on one
processor, but it does not seem to be eating up memory (swap memory does
not change). I've also tried to run tleap in a pbs job asking for 1Gb of
memory and still I get a segmentation fault.
I've also tried to add Ions one by one but it does not seem to matter.
What seems strange is that the charge calculation over the grid is
completed and only after the ion is placed the segmentation fault happens.

I also remember working some while ago with larger files than the present
one and never got a segmentation fault.

I know this sound very imprecies but I'm looking for help to find a
starting point to try and trace this down.

Thanks,
Ioana
