3. What did you do?

First of all I was not able to reproduce this error ever again It was an one-off thing and when I googled the error only the source code came up, so reporting.

It occurred when I was doing go build on(&to) darwin/amd64.

4. What did you expect to see?

go build to work.

5. What did you see instead?

$ go build

The signal is SIGWINCH which is normally sent when the window size changes. Where you adjusting the size of your terminal window when it happened?

@ianlancetaylor yes, I was running iTerm2 and just hit Cmd+D which would split my terminal emulator window horizontally into two. This effectively shrinks my current terminal window where the go build was running.

I just ran into this too, with go go1.6.2 darwin/amd64 by maximizing the iterm2 window during go build. I'm able to consistently repro this behavior.

It's hard to imagine what the non-Go code is that changed the signal handlers. The obvious answer is the C resolver that the go command is linked against for 'go get'. But this was a 'go build' command, so it shouldn't have been doing any network work at all. Even so the code was there. I tried running a go build github.com/Azure/custom-script-extension-linux/... and send it a SIGWINCH while running and could not reproduce this, neither at tip or at go1.6.

It could be that if there is some C-created thread without a sigaltstack and it takes the signal but runs Go's signal handler. That would crash this way. But I don't see where that C-created thread is coming from in cmd/go.

@ahmetalpbalkan, what version of OS X are you using? Any fancy network firewall or other software?

@rsc this was a pretty standard OS X 10.11 El Capitan setup with go1.6.2 installed via Homebrew. I am now trying to reproduce this on macOS 10.12 Sierra with go1.7.1. It no longer reproduces. It used to repro very easily by splitting iTerm2 windows while go build was running.

I don't think this issue is important enough to investigate deeper. Closing. Thanks for taking a look.
