These options break the dyld linker cache on macOS Big Sur, which in turns means it fails to load system libraries on startup, which means no app can work.

LUAJIT_ENABLE_GC64 obviates these options, so make sure not to set these options if GC64 is enabled.

See annoyed Twitter rant at https://twitter.com/nevyn/status/1331217137889931269.

See Mark Rowe's reply (who is an ex-Apple/Google engineer) here: https://twitter.com/bdash/status/1331288345498980357 There is a share region overlap, which disables the dyld cache, which makes system libraries unlinkable, which means executables can't start.
