Under some configurations, which cause heavy VM paging, there are comparison failures. Under other configs that don't stress the VM so much, it works correctly. My coworkers think this could be a bug in Leopard's VM implementation. If that's the case, Apple certainly needs to know about it, but the bug is difficult to reproduce - one has to leave the tool running for hours, for example. Whether it's Apple's bug or mine, I certainly want to find the cause. I'm not sure how to proceed. Can anyone give me some debugging tips?
