By adding noinline and calling fprintf before returning we ensure that every function will have a distinct call frame and that the return address will always be saved instead of saving the target in main as the result. Before this change all backtraces were always backtrace -> main -> _start, i.e. always exactly three entries. This happenend because all calls were inlined in main() and the test just happenend to pass because there is at least _start before main. I found this while fixing some bugs in libunwind for CHERI and noticed that the test was passing even though the code was completely broken.
