The link below is a relatively simple example of differential fuzzing between implementations in different programming languages using AFL. It works by reading and writing to a second process it spawns and aborting on differences. Before writing this, I could not find any working examples of this technique, although I'm sure they are out there, somewhere. https://github.com/ironmeld/doubleback/blob/main/src/c/tests/dfmt_fuzz.c https://github.com/ironmeld/doubleback/blob/main/src/c/tests...
