In what context is this code running?  If the data declaration is outside
of a function (global space), then it should be allocated correctly but
you'll also end up with a 40MB+ EXE file.  If you have this code contained
in a function (local space; say main function), then you're trying to
allocate 40MB of stack space which I'm sure almost any compiler wont let
you do (easily at least).  You may wanna try this instead.

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char **argv )
{
   int *buf = ( int* )( malloc( 10000000 * sizeof( int ) ) );
   int i;

   /* code to print contents of buf */

   free( buf );

   return( 0 );
}
