__endless_loop__ is placed in section .fini0 (the last of the nine reserved
finalization sections). One way it can be reached in a normal application
is falling off the end of main(). It is what follows any other
finalization routines, including __stop_progExec__, which is normally empty
and appears in section .fini9. __stop_progExec__ is jumped to by exit(3c)
if the macro definition of exit() from stdlib.h in msp430-libc is invoked.
So: Returning from main(), invoking exit(3c), or other magic that causes
code to jump into the finalization sections.
