> I'd to try building ECL + Maxima with the low memory access threshold
changed. This requires root on the machine in question (but it's a simple
change and easy to make permanent on reboot). I haven't asked Mariah about
the possibility of doing this yet.
Well, this would probably prevent us from testing other, perhaps better
solutions... ;-)
Similar machines will likely have the same problem, and I'm not sure
whether everybody would lower the mmap min address since this is
considered a security hole, at least in theory. And not every Sage user
having access to such a machine will be able to do that, or to persuade a
sysadmin to do so.
If `mmap()` is really the problem, one should be able to perhaps tweak /
patch `configure`, or convince ECL in a different way to not (try to) use
such low addresses. Furthermore, if that's really the cause, it is
certainly a bug ''how'' (or when) ECL fails.
