cmd/go: ignore SIGQUIT #3581
Labels
Milestone
Comments
oh! that's what's happening. Yes, I was using "go run x.go" here. You could imagine cmd/go catching SIGQUIT and relaying it to the child and letting the child exit fully before handling SIGQUIT itself normally. Or something. But at least I understand the workaround now. (not using go run) |
