That's my understanding as well.
I also got the impression that they'd already hit a significant inflection point with csmith as the bugs it was finding were ultimately duplicates of issues it'd already found. csmith was going to need some significant development to find new ways to stress compilers. I have a lot of respect for John's work. It's too bad I don't see him more often. He's only 15 minutes up the road working with my old group at the U. jeff
