If you are using C++, then the answer is simple:  gcc builds static
arrays into the executable when compiling a C++ program.  If you declare
something like:

static int global_array[1000][1000];

All 4 megabytes of the array will be included in the executable file. 
See chapter 8.14 of the DJGPP FAQ for precise details and instructions
on how to keep this from happening.
