What did you do?

just run go build

What did you expect to see?

build successfully

What did you see instead?

I think this is the first compile today. I go to an old project which last build 3 days ago. then

go build

Is this repeatable at all?

Signal 28 is SIGWINCH, which is sent when the window size changes. Did you resize your window during the build? (Resizing the window should work, of course, I'm just trying to figure out where the SIGWINCH came from.)

[lunny]

@davecheney I didn't
@ianlancetaylor I think I didn't. I just opened iTerm2 and cd the project directory and type go build.

What does this command return? sw_vers -productVersion

@lunny, was this reproducible? What about if you intentionally resize the terminal while building?

@ianlancetaylor, dup of #18600?

[ianlancetaylor]

Yes, I would guess this is the same as #18600.

[aclements]

Closing as a dup of #18600.
