Ohhhh..... segfault whack-a-mole!

Been there... I was doing the high verbosity in an attempt to find out if our file might be somehow the problem.

The example works for me with sander and sander.MPI and segfaults for
pmemd, only, is this what others are seeing?

As for pmemd, Ben Roberts and I threw a night into hunting this down at the
Amber meeting without any success. The error surfaces in (I can't say it
starts in) extra_pnts_nb14.F90, init_extra_pnts_nb14. The segfault occurs
on a deallocate call (line 649) according to my debugger, but the error
occurs earlier. Ben and I tried a lot of things to just see where the
error was occurring, but the error occurred in a different place every time
we tried something new.

I know this is super helpful.

All the best,
Jason
