Hi gophers, I faced a strange problem： os/exec always fails with `fork/exec /usr/bin/qemu-img: invalid argument'.
Simplified code is at https://play.golang.org/p/v1APfzmS2p9. It seems this simplified snippet runs well without errors, but my real code is no more than just some variable initializations than this snippet. So I suspect it's the context's problem, but my context is too complex to simplify and put onto the playground. What I can think of that what might be linked to this error is that this function is run in a goroutine. But I did write a simplified goroutine version, sadly it worked well too... I had no idea how to do further debugging. And further, the executable is not to blame, it fails with the same error even if I substitute the executable to `ls' or anything else. Can you provide me some suggestions to the possible reason or the way to debug? Thanks.
