John,
"Mission creep" is a bit strong. Csmith is a random program generator and memory unsafety is an almost trivial variation on the existing theme.
Before we start talking about mission creep perhaps the csmith developers ought to decide on what its mission is. To me the proposed additions are within what I see as its mission. -- Derek M.
