It's *not* the same software. MacPorts has GNU bc 1.07 which is
licensed GPL-3. macOS used to have GNU bc 1.06 released back in 2000
under GPL-2. Apple has switched to someone else's bc implementation in
recent macOS probably because as we know Apple is allergic to GPL-3.
The macOS bc is Gavin Howard's version which is also used in FreeBSD. It
integrates both the GNU additions to the POSIX-standard bc and its own
additions, some of which came from the original BSD bc. There has been a
steady trickle of bug fixes since the version Apple ships on Sonoma,
some of which reference macOS.
Looking at the man page, I'd bet that exiting when the terminal geometry
changes is understandable, since making that change sends a WINCH
signal and bc resets on signals for which it has no handler. That gap
seems like a bug to me, but one to report to the author or Apple.
