Also "horribly written code." I've been playing around with some code from 1993---the Viola web browser (one of the first graphical web browsers). Ooh boy was it fun when I ran it with "-pedantic -Wall -Wextra". Hundreds, if not thousands of warnings. A ton of unused argumetns, implicit declarations (no prototypes), unused variables, return type not specified, a few "control reaches end of non-void function," some format string mismatches. Pretty much what you would expect from K&R C (the code paid some lip service to ANSI C, but not a whole lot). Also, the code runs (not well, but it does) on 32-bit systems, but immediately crashes on a 64-bit system. That's because of the whole "int==long==ptr==32 bits" that permeates the code.
