examples/burgers_3d_cubedata not working

[rjleveque]

On the master branch @826b95c0df7, examples/burgers_3d_cubedata gives this error:

Reading data file: setprob.data
         first 5 lines are comments and will be skipped
 Storage allocated...
there are    1 grids with     8000 cells at level   1
  error in filrecur - level 1 not set
  should not need more recursion 
  to set patch boundaries

@mjberger are you getting this error too?

I just ran this and found

there are    1 grids with     8000 cells at level   1
At line 69 of file /Users/mandli/src/clawpack/amrclaw/src/3d//intfil.f
Fortran runtime error: Index '0' of dimension 2 of array 'node' below lower bound of 1

might be a clue.
