Purify was a fantastic tool and I would have cheerfully paid $100K in late-90's dollars. We demoed it and the amount of memory errors it found in our legacy C and nascent C++ code stack was simultaneously depressing and exciting. We bought licenses and went to town. There was a markable product quality improvement as a result, at a time when our sales were exploding. I've never found a memory tool since that was as capable. We were running SGI IRIX boxes at the time.
