Comment 1:

It's hard to say without an example narrowing down the problem.
There have been some changes involving what code points we accept when, and also with
what we quote and how.

Labels changed: added priority-later, removed priority-triage.

Status changed to WaitingForReply.

I have run
package main
import "fmt"
import "io/ioutil"
func main() {
      s, _ := ioutil.ReadFile("/tmp/node.png")
      fmt.Printf("package main\nconst s = %q\n", s)
}
on both images and the result was a compilable Go source file (with Go 1.0.3) in each
case.

Comment 3:

Yeah, I can't reproduce either.  I think it was the go tool (go/parser) as part of "go
build" and +build scanning that was failing, not 6g.  gofmt was also failing to reformat
it, suggesting the same.
But I can't reproduce that either.
But I saw it and worked around it, so I'll try more.

Comment 4:

Who knows.  Closing, since I don't have time to figure out how this happened.
