  I note with bemusement that you've went into great detail about the
machine you are using, but didn't bother to mention the somewhat
important details of how much memory your system has and how the
per-process limits are configured by default.  That would certainly help
to diagnose the problem.

  A few other questions I have -- (1) Are you ever *freeing* any of the
pointers that you are allocating?  (2) When you say that you are
allocating "pointers", do you mean that you are allocating space for
things like structures and then assigning the address of that allocated
space to a pointer?  (3) What are you using for allocation, malloc?  (4)
What error do you get when you can no longer allocate -- out of memory,
or something else?
