Do you mean that with 128*1024 compilation
sometimes succeed but sometimes not?
What are the error messages about?

Why not. But it seems that GCL/Maxima loads init.lsp
only from current working directory or if explicitly
requested by appropriate command line parameter.

I don't have it. GCL has quite complex memory
allocation system. It splits memory in several
independent areas and  it is hard to make any
universal layout. Optimal memory allocation
in GCL seems to be problem dependent (do you
need many large bignums or lots of list nodes).
This is my practical experience so far
but actually I'm not 100% sure that I'm correct.
Maybe the right way is to tune automatic new
memory allocation using allocate-growth rather
than preallocate large amount of RAM on
start up.

All memory allocation functions are described in
GCL info pages.
