If you open the Extended Detail pane, you can get a full stack trace for each one of these occurrences, and you can double-click one of those frames to have it display the source file inline right in Instruments with the line at which the object was released, retained, etc. highlighted.
Thank you, Charles. I've filed that advice away and hope that I never need to use it.
I've had mostly negative experiences with Object Allocations – execution slowing to a crawl, consuming memory until, it can't get any more, then crashing. Your description of all it does kind of explains why. In contrast, my brute force method only logs for one class.
But maybe since I have a big 64-bit Mac now with whoopee 4 GB of RAM, it will work better.
