I do not even know if I am connecting the problems correctly. Here
is what Vadim wrote on a "The CONS storage exhausted" problem, back
on August 18, 2003:
"Maxima's background lisp GCL has compile time maximum
memory limit. Default value - 32K pages which amounts to
~128Mb of RAM. Your computation exhausted all this
memory. Take a look at the output generated by the command
:lisp (room)
If your really need more RAM for your should rebuild
GCL with --enable-maxpages=64*1024 or some other
greater value and use this new GCL to rebuild Maxima."
I don't really know anything about these issues.
