source window becomes blank with cgo compile warnings

[aletheia7]

What did you do? (required. The issue will be closed when not provided.)

I was editing a go file and issued :GoInstall The problem is repeatable. It seems that cgo compiler warnings can mess with the vim/vim-go errors interactions. The problem only occurs with one app.

I use vim-go all day long. Thank you for making vim-go.

What did you expect to happen?

The go source would remain present as usual and go syntax errors would show-up in the vim errors window.

What happened instead?

The go source code disappeared (window was still present) and the errors windows was populated with three lines.

I think the problem is triggered by the following go install -v output:

$ go install -v
# <redacted>/vendor/github.com/google/gousb

                  ^~~~~~~~~~~~~~~~

Configuration (MUST fill this out):

• vim-go version:

  afbfc37 (latest)

• vimrc you used to reproduce (use a minimal vimrc with other plugins disabled; do not link to a 2,000 line vimrc):

I can comment-out all plugins except vim-go and the problem still occurs.
