I'm debugging the following go program on MacOS 10.14.6.
package main
import (
"fmt"
"os"
"os/signal"
)
func main() {
sigs := make(chan os.Signal, 1)
signal.Notify(sigs, os.Interrupt)
sig := <- sigs
fmt.Printf("Got a signal '%v', start shutting down...\n", sig)
}
The program waits for the SIGINT and exits. I'm sending SIGINT via `kill -2
<pid>`. Attached logs show that debugserver notifies go debugger that the
program got SIGINT (`$T02` package), go debugger responds with `vCont;C02`,
debugserver receives the packet, but doesn't call `MachProcess::Signal` and the
program doesn't get the SIGINT.</pre>
