There should usually be an -auto flag on the setup command line.

Note that 

 ./flash4 flash.par

is not the way to specify a parfile foe a FLASH run. The following should 
work:

 ./flash4 -par_file flash.par

Since 'flash.par' is the default name for the parameter file, it does not 
really matter either way, as long as that is REALLY the name of the file 
you want.

The code statement beginning on line 584 should be:

                       scrch_Ptr(HY_VAR2_SCRATCHCTR_VAR,i,j,k) = &
                            0.5*( scrchFaceXPtr(HY_N05_FACEXPTR_VAR,i,j,k) &
                                 +scrchFaceXPtr(HY_P05_FACEXPTR_VAR,i,j,k))

it is not clear to me under what circumstances the variable i could exceed 
the 'upper bound of dimension 2'.

I notice that your compiler version is by now rather old - it is 
older than versions for which we do regular testing. Could you try 
with a newer version of GFortran?
