Stack Clash Coroutine Demonstration

Full article: Stack Clashing for Fun and Profit

Instructions

You'll need a C99 compiler and your favorite make:

$ make -k

If there's no compiler named c99 on your system:

$ make -k CC=clang
$ make -k CC='gcc -std=c99'

If your system doesn't support the <ucontext.h> XSI extension then one of the binaries will fail to build, which is why the -k option is useful.
