Well, I upgraded to 6.1 and now I can get heaps bigger than 500MB.
However, I upgraded Matlisp at the same time that I upgraded Lisp, and
now I'm running into a new problem. Well into a several-hour run (but
beyond the place it was crashing before) Lisp crashes with "corrupted
internal data structures". It gives me no debugging options other than
dumping core, and then gives an illegal instruction when it tries to
dump core.
The error message advises checking "foreign functions and code compiled
with high speed or low safety". The only such code in my program is in
Matlisp. I've copied a 6-month old Matlisp directory from another
machine and rebuilt it for ACL 6.1, and I'm running using that. We'll
see if I still get the problem.
