I'm not sure I am understanding what you are trying to do.

Subject: Re: [Jprogramming] Fwd: Do "Out of memory" errors vary by J
implementation?
Out of memory errors are notoriously hard to debug; if you need to run this
program on any different data than what you're using now I'd take up the
offer to come up with an alternate approach.
By the way, it's common for different oses to display different behavior
under pressure. Windows fails early; Linux kills random programs later.
Dunno what mac does.
