Illegal instruction: 4

[avh4]

On Mac OS, 10.10.5 2.8GHz Intel Core 2 Duo Mac (edit: apparently related to CPU, not OS version), Elm dies with Illegal instruction: 4:

$ elm-make --version
elm-make 0.18 (Elm Platform 0.18.0)
$ rm -Rf ~/.elm
$ mkdir tmpdir && cd tmpdir
$ elm-make --yes
Starting downloads...

Illegal instruction: 4
$ echo $?
132

Inspecting the network traffic, this appears to happen after elm-make successfully downloads the package index and the elm-package.json for elm-lang/core 5.1.1, elm-lang/html 2.0.0, and elm-lang/virtual-dom 2.0.4.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

The same issue occurs on Mac OS 10.11.6

This appears to be possibly related to the CPU model, not the OS version.

The problem occurs on 2.8GHz Intel Core 2 Duo Mac (OSX 10.10.5, or OSX 10.11.6).

And does not occur on 1.4 GHz Intel Core i5 Mac (OSX 10.10.5).
