I&#x27;ve always thought that there would be more value in exactly the opposite - a pathological C compiler (or C++ compiler, POSIX operating system, etc.). The pathological compiler would always implement undefined behavior in the most surprising, unpredictable manner - e.g., uninitialized memory would have a properly randomized value that changes from one run to the next, overflows would result in random values, etc.<p>That way, any programs that are made to work on the pathological implementation are largely guaranteed to rely only on standardized behavior, and work on any other standards compliant implementation.
