I have installed 5.14.0 on SBCL on my machine, and I also converted the
argument to exp into a float. The combination has fixed several problems.
1) My SA code now runs quickly and cleanly on all test optimizations
that I have thrown at it (including some fairly complicated ones
involving minimax type criteria).
2) C-c C-c in emacs now stops maxima without causing a crash. previously
under GCL it would often complain about "memory may be corrupted" and
indeed it would rarely proceed.
3) Things run faster in general it seems.
My vote is to move to SBCL as the standard platform as soon as a 32 bit
windows version can be reliably had.
