Details:

I was programmatically creating several script files that had the output of an
unrelated program  and Octave code to further manipulate them, essentially
being self-contained scripts with both code and data, the data coming from the
upstream program. One of those script files was over 1GB because it had that
much data. Upon invoking that script, Octave crashed with no warning. I was
monitoring memory usage through top, and it never exceeded 9%, but it crashed
none the same and sent me back to the bash prompt.

I can work around this, but I wanted to report this data point about the limit
of what the interpreter can handle. The file which crashed had one matrix of
size 19100000 x 12, each element being a positive integer from 1 to 3320. The
only code was "arr = [" at the start and a closing "];" at the end.
