Lua (luajit), 52 bytes

function f()coroutine.resume(coroutine.create(f))end 

An attempt to compete for the bounty that was recently set on an answer in Lua. This is a function submission (basically because I had to define a function anyway, so not including the code to run it saves bytes).

The program works by creating infinitely many coroutines, suspending each in turn to create and start the next. The most commonly used Lua interpreter, lua, thought of this case and starts causing coroutine creation to fail after a while. luajit, however, segfaults. (Valgrind reports the issue as a failure to grow the OS-defined stack; this is believable, seeing as one common coroutine implementation gives them each separate parts of the stack.)
