I first learned about this in high school from "A Basic Just-In-Time Compiler"[1]. It was mind-blowing that you could just cast some data storing machine code to a function pointer and execute it. Trying the program now it seems GCC no longer accepts it with -pedantic-errors because casts between object and function pointers are, according to the standard, implementation-defined.
