Comment (by flwyd):

 Possibly related, I get a segfault whenever I run macports-installed
 neovim on macOS Mojave 10.14.6 (Intel chipset) with a stack trace
 implicating luajit:

 Running `nvim` brings up the basic vim UI, but doing almost anything, like
 moving one character or even running `nvim --version` will generate a
 segmentation fault.

 I tried deactivating `luv-luajit` and installing `luajit-openresty` as
 mentioned by Brian, but `port install neovim` still seems to require `luv-
 luajit`.

 What would be required to fix `luv-luajit`?  Alternatively, could the
 Portfile switch to `luajit-openresty` if fixing luv isn't faesible?
