It's hard to know if one doesn't have the problem or whether the leak is just running so slowly it doesn't crash Vue before you exit. A good guide is the system resources figure in the options panel. Before I had crashes, I never looked at this. Maybe it was starting at 60% and leaching away so gradually I never saw that it was down to 30% by the time I was done. With some recent files I've been working on, it starts at 30% and loses 5% per operation, even if that's only shifting the camera.
