Gee, I'm sorry you thought I was being "snippy".  You apparently missed
that I was just providing you with some obvious advice.

You state that this is a "rather serious problem".  It seems like if this
was a really serious problem you'd be actively working towards solving it
rather than sending out email and hoping to get lucky.  If you think it
is malloc that is causing the problem then instrumenting malloc to prove
your assertion is not that much work.  Building the dll is probably not
five commands but it is not a heck of a lot more than that.
