                  This is the memory allocator.&nbsp; When asked to allocate a
                  buffer, allocate it in such a way that the end of the buffer
                  is followed by an inaccessable memory page.&nbsp; If software
                  overruns that buffer, it will touch the bad page and get an
                  immediate segmentation fault.&nbsp; It&rsquo;s then easy to
                  zero in on the offending code with a debugger.

                  There are a few complications.&nbsp; If the user asks for an
                  odd-sized buffer, we would have to have that buffer start on
                  an odd address if the byte after the end of the buffer was to
                  be on the inaccessable page.&nbsp; Unfortunately, there is
                  lots of software that asks for odd-sized buffers and then
                  requires that the returned address be word-aligned, or the
                  size of the buffer be a multiple of the word size.&nbsp; An
                  example are the string-processing functions on Sun systems,
                  which do word references to the string memory and may refer to
                  memory up to three bytes beyond the end of the string.&nbsp;
                  For this reason, I take the alignment requests to memalign()
                  and valloc() seriously, and
