I've seen #63, but this seems more severe as it happens for me even on a very basic script:

$ cat foo.js
console.log('hi');
$ node -v
v18.15.0
$ 0x -v
0x 5.5.0
$ DEBUG=0x* 0x -o foo.js

Ha, this is because I'm using a weird shell + terminal emulator (eshell). https://www.gnu.org/software/emacs/manual/html_mono/eshell.html#Visual-Commands describes the problem here. Never mind, thanks for the great tool!
