Ah, now it makes sense. I thought it was trying to tell me that the
actual creation of the object was causing the memory leak!
Now to the hunt!

for concern as the memory used may keep increasing.

I've just switched over to using FastMM4 in a Delphi 6 project and I'm
getting a rather HUGE list of errors logged to a file when the program
ends (which is fine). But I can't get my head around what the messages
are telling me. There are a lot of this kind of message:

But I don't understand why this would be happening? It's just a simple
construction chain with parent objects creating child objects in their
constructors. There's no tricky pointer operations going on or anything
strange - just a bunch of objects being created. It appears from the
stack dump that it's the Memory Manager that has the problem - can
anyone shed any light here?
Phil.
