did u try allocating it the dynamic way??
via a call to malloc or in a similar fashion?

Re:

here 's an example of static and dynamic allocation...
(my prev example was only about single dimensional arrays...)

a 2dimensional array of  4450 x 4450
(change the dimension to 1450 x 1450 if  u find the
first size to be too big)

TEST.C
#include <stdio.h>
int main()
{
  double a[4450][4450];

  a[4449][0] = 999;
  printf( "%lf\n", a[4449][0] );
  return 1;
}


TEST2.c
#include <stdio.h>
int main()
{
  double **a;
  int i;

  a = (double**) calloc( 4450, sizeof(double*) );
  for ( i=0; i <1450; i++ )
  {
    a[i] = (double*) calloc( 4450, sizeof(double) );
  }

  a[4449][0]=999;
  printf( "%lf\n", a[4449][0] );
  return 1;
}

It may help to run the program being debugged on a separate X display
to the debugging tools, so that you can more reliably control what
events it receives. If you debug it on the same display, its hard to
avoid the program receiving expose, enter/leave, focus etc events as
you use the debugging tools.

You don't need a second machine; an Xvnc session will do.
