above were in response to questions I had asked him regarding
difficulties I had with the Debian maxima package. I had forgotten
the following detail, which might provide us with a clue:I am afraid that change is necessary at least for the current
implementation in GCL. Basically it is so we can use the strategy
for garbage collection. I will try to convince the gmp authors to
make the change. Also I would like to use a relocatable space
strategy for the bignums, but that will require some more minor
changes to gmp. I think I have almost made them, but there is at
least one that is illuding me. [ (si::SET-GMP-ALLOCATE-RELOCATABLE
t) will switch to relocatable, but some random bugs will appear if
you compute a lot!]
