Re: gnat and heap size

It would help to know what hardware/OS this is trying to run on since this
sounds like it is probably running up against some system limitation. Things
like VMS had virtual memory restricted by various settable parameters, so it
*might* run if the quotas were increased appropriately. But you'd need to
know the system to make the recommendations.

It wouldn't necessarily have to be a kick-a** machine to run something
needing 800mb of memory. Assuming it had virtual memory and sufficient disk
space, you might be able to get it to work. Albeit, the page swapping would
probably kill you, but it might actually run in a finite amount of time.
Virtual memory can be a cool thing if you're not in a big rush.

If virtual memory didn't exist, we'd have to invent it.
