This correctly diagnoses undefined behavior in that C function. I didn't investigate what happens on that platform is as it's easier to fix the problem on all platforms. I propose installing the attached obviously-safe patch into the emacs-27 branch.
There were several deprecation warnings when compiling but I assume we don't care about them in this older branch.
"make check" reported four unexpected failures. Perhaps a macOS expert could be persuaded to look into them. A tarball of the failed logs is attached.
