@l2dy Sorry for assigning this one back to you as it must have been caused by ​macports-ports#11168. I can't look into this at the moment.

I know there had been problems with lua vs. luajit in the neovim port before... but can't remember any details.

[l2dy (Zero King)]

Try port deactivate luajit and then port install luajit-openresty, this should fix it.

I'm looking into this.

Looks like the luajit port we have is problematic, but luajit-openresty is not (it does not crash with ASan).
