One way to overcome the problem is NOT to declare a large amount of memory
as global data!  I know, I have had the same problem as you.  What I did was
to allocate the global data during run-time, and declare the pointer to that
allocated memory in global data.  That works out quite well- especially since
both global data and run-time allocated data are both placed in the heap
portion of the code.
