I'm using windows vista, 32-bit, AMD Sempron processor. I used the
installer to install, didn't mess with the installer default settings,
used SSE2.

Octave seems to have great trouble when it wants a lot of memory. At
some point it crashes. Sometimes it will save the variables before
crashing but most of the times it won't.

Specific cases of where it crashes, I don't have. It's not
reproducible. It's just when working with a lot of data (for instance,
over 100 MB total memory consumption reported by whos) that it will
crash after a while.

Also, gnuplot will always crash when I run "close all".

And today I got something I've never gotten before, note how the
variables are all there in one minute and 2-3 commands later they're
all gone without any way to get them back, all my work lost:
