Is the source of the code you are compiling available so I can try to
reproduce this bug?

What did you do?
If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

go install my package

cc @crawshaw -- the panic is probably from decodetypeKind in this line:

            if decodetypeKind(s)&kindMask == kindInterface {

+1. Same error. Trying to build an otherwise working program with go:binary-only-package in official docker.

go version go1.7.1 linux/amd64

@mandeepbrar want to try out https://golang.org/cl/29692? It's designed to fix #17140 but the diagnostics change may mean you get further into linking before an error.

@crawshaw Seems to go a little further, but an error again

Does anybody have a repro here?

I'm going to kick to Go1.10 since we don't have one yet.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
