Suspending client on start leads to the process quitting #3701

Open lenormf opened 4 years ago

lenormf commented 4 years ago

Might be a duplicate of #3069.

I was trying to start a client in the background, and send it files to open via kak -p, from the same shell.

Steps

I could also reproduce the behaviour by typing the keys "bg" right after the first step above.

Outcome

The whole terminal/shell gets closed, along with Kakoune.

Program received signal SIGHUP, Hangup.

[Inferior 1 (process 784792) exited with code 0377]

Expected

The server runs in the background, no UI is shown on screen, the shell remains usable.

Running kak -n & closes the shell now.
