The following very simple program:
--------------------------------------------------------
int main(int argc, char *argv[])
{
    //
    int ttt[1073741824];    // fails --> segmentation fault
    //int ttt[1048576];    // ok
    //
    return 0;
    //
}
--------------------------------------------------------
segfaults when an array of 1Gig ints is declared.

--------------------------------------------------------
(gdb) b main
