I'm getting a "segmentation fault" when I run the following command:

----------------
sander -O -i md.belly.in -o md.belly.out -p polyAT.prmtop -c
min.belly.restart -r md.belly.restart -x md.belly.traj &
----------------

The input file is:

----------
5DNB, initial dynamics w/ belly on DNA, model1, 9.0 cut
  &cntrl

   ntpr = 10, ntwx = 500,

   ntf = 2, ntb = 2,
   cut = 9.0,

   ibelly = 1,

   nstlim = 12500,
   nscm = 0,
   dt = 0.002,

   temp0 = 300.0, tempi = 100.0,
   ntt = 1,
   tautp = 0.2,

   ntp = 1,

   ntc = 2, tol = 0.0005,

  &end
  &wt
    type='TEMP0', istep1=0, istep2=500,
                  value1=100.0, value2=300.0,
  &end
  &wt
    type='TEMP0', istep1=500, istep2=12500,
                  value1=300.0, value2=300.0,
  &end
  &wt
    type='END',
  &end
  &rst
    iat=0,
  &end
Allowing only the water and counterions to move in the belly
RES 21 3547
END
END
----------

and the output file (before it crashes, anyway) is (note the excess
spaces at the end):

  Here is the input file:

  &cntrl

 

   ntpr = 10, ntwx = 500,

 

   ntf = 2, ntb = 2,

   nscm = 0,

   dt = 0.002,

 

   temp0 = 300.0, tempi = 100.0,

Can anyone see what's causing this?
