Whoa! Well, nothing in the core driver has been changed in the version 0005
release, certainly nothing related to memory usage/allocation. In fact,
nothing has been changed along these lines since like version 6.30.0250 or
something.
Something to keep in mind though, if the driver is *NOT* using the "Use
Declare/Fetch option", then the driver will attempt to store the entire query
results in its memory. Is it possible your usage test would have done a huge
query or something like that? The Use Declare/Fetch option only allocates a
cache of 100 rows (by default) and never goes over that so huge queries
wouldn't bother it.
If there is a memory problem like this in the driver, I would like to know
more about your test so I can track it down. If so, you might try changing
some options (such as the Declare/Fetch) and see if it changes anything.
