Comment:
{{{
[10:28pm] mabs: mhansen: I need to look at John's patch to make 100% sure
they
are both fixing all the same issues (besides John's patch doesn't address
the
signed int problem)
[10:31pm] cwitty: I think the point of #5273 is that the error message on
a
matrix of size 2^80 on a 32-bit computer suggests that it might actually
work
on a 64-bit computer.
[10:31pm] mabs: Yes. That is why I thought something else remains to be
done
[10:32pm] cwitty: But if you're going to worry about that... I'm pretty
sure
there's no computer in the world that can handle a matrix with even 2^50
entries...
[10:32pm] mabs: cwitty: Can you integrate that change on top of your
change.
[10:33pm] mabs: Well, you can create the MatrixSpace
[10:33pm] cwitty: True.
[10:33pm] mabs: Not that it will not blow up if you do anything serious
with
it, but if things are very sparse it should not appear to work
