Intel Fortran compiler 2013 (Visual Studio2010): best way to increase stack for long scalar strings

问题

I was having a stack overflow error in a fortran code compiled with fortran compiler 2013 and VS2010 under windows 7. I first try to set HeapArrays=0 in Project Properties ->Fortran -> Optimization -> Heap (Allocates temporary arrays of size n in the heap rather than in the stack). In that way all the arrays should move to the heap. However, nothing changed and the stack overflow error was still there. Then I added the flag /stack:2000000 in the Link Options and now everything runs smoothly. Why HeapArrays=0 does not work? I have a bunch of character*2650 declarations, both in the main code and in subroutines. Is it possible the declarations in the main code are not considered "temporary arrays" ? The stack overflow error shows up right at the beginning.

EDIT: this is my declaration in the main program. I have similar ones (but shorter ) in subroutines:

character*2560 DOScallINV,FORMdosCALLtxt,FORMdosCALLinv,filenam,FILEinv,provSTR,FMTtimeMETEO,&
            TIMEstring,fmtGRID,fmtTIMEstring,FMTdataMETEO,WORKINGdir,path,DIRgribs,PATHgribs,&
