STORAGE_ERROR : EXCEPTION_STACK_OVERFLOW

["Robert C. Leif" <rleif@rleif.com>]

   I am creating software in Ada to visualize images obtained with a
fluorescence microscope. Unfortunately, when I switch my images from having
16 bit pixels to 32 bit pixels, I raise the exception STORAGE_ERROR :
EXCEPTION_STACK_OVERFLOW.
   I am using GNAT 3.15p.
   The Users Guide to Windows states: "5.3 Setting Stack Size from gnatlink 
   It is possible to specify the program stack size from gnatlink. Assuming
that the underlying linker is GNU ld there is two ways to do so: 
   using -Xlinker linker option 
     $ gnatlink hello -Xlinker --stack=0x10000,0x1000
   This set the stack reserve size to 0x10000 bytes and the stack commit
size to 0x1000 bytes. 
   using -Wl linker option 
     $ gnatlink hello -Wl,--stack=0x1000000
   This set the stack reserve size to 0x1000000 bytes. Note that with -Wl
option it is not possible to set the stack commit size because the coma is a
separator for this option."
   My project file includes:
   
   package Linker is
      for Default_Switches ("ada") use ("-g", "-Xlinker
stack=0x10000000,0x10000000");
      end Linker;
   
   Even with a 10 megabyte stack, I still get Stack_Overflow.
   Any suggestions would be greatly appreciated.  I believe that I know how
to put the array on the heap using an access type.  However, I greatly
prefer working with objects that are on the stack and omitting pointers from
my code.
   Thank you.
