Hi Sam, I'm running 1.10.3 on High Sierra, installed via brew.

Here's some more helpful output:

➜  awesomeProject go version   
go version go1.10.3 darwin/amd64
➜  awesomeProject gofmt test.go

package main

var m_19_chars = map[string]int{
 "i":   0,
 "iii": 0,
 "iiiiiiiiiiiiiiiiiii": 0,
}
var m_18_chars = map[string]int{
 "i":                  0,
 "iii":                0,
 "iiiiiiiiiiiiiiiiii": 0,
}
var m_19_chars_reorder = map[string]int{
 "i": 0,
 "iiiiiiiiiiiiiiiiiii": 0,
 "iii": 0,
}
