One of the gnarliest code bases I ever worked in was a very large C project where the inner core had been run through a f2c transpiler. Over the subsequent decade the surrounding code was a hodgepodge of people taking their own interpretations of autogenerated C code because folks didn't question why the code looked the way it did and thus they did their best to maintain the same look and feel. Oh and no one really knew how that original inner core worked, there were no docs, no oral tradition, and it was over 20 years old. While I was still working there we accumulated enough major change requests to the application that finally got the go ahead to throw the original code base out and start from scratch.
