I get the following error message:

zsh: illegal hardware instruction  dark-mode status
$ dark-mode --version
2.0.1

The program takes a few minutes to produce the error message. dark-mode on also takes several minutes to run but doesn't produce any output and doesn't enable dark mode. Everything worked fine yesterday.

I should probably clarify that this is on macOS 10.12.6.

The error goes away after a reboot, but then reappears seemingly randomly after a while.

Code that caused this was seemingly removed in 40dbfce (included in v3.0.0) so this issue should probably be closed.
