Please notice that you will not be able to allocate single 2.5Gb array, as those 3Gb of address space is somewhat fragmented. But you definitely will be able to allocate 50 arrays, each one is 50Mb is size. If you'll look at the TBGEN sources you'll see that it uses double indirections to address bitvectors on 32-bit systems to avoid exactly that problem. Thanks, Eugene
