[sorry, getting slightly offtopic]

If what you are reporting as `SIZE' is the maximum memory footprint of
the application, then I am not that surprised.  The malloc in Linux
libc and glibc (by Doug Lea) is heavily optimized for memory savings
(while remaining quite fast as well).  I haven't seen a malloc version
that performs better in this respect; see

  http://www.dent.med.uni-muenchen.de/~wmglo/malloc-slides.html

for some comparisons (Solaris isn't yet covered in my tests but will
be soon).  You might want to use Doug Leas malloc on Solaris as well
and check whether your SIZE goes down...

Wolfram.
