Subject: 28.0.50; emacsclient Invalid socket owner error in gccemacs
Date: Thu, 22 Oct 2020 02:32:04 -0500

The emacsclient binary produced by the native-comp branch cannot connect
to the server. When a connection is attempted, the error message
"emacsclient: Invalid socket owner" is displayed. I have 27.1 without
native-comp installed, and that emacsclient can connect to the
native-comp server without issue.

The error is the result of a failed uid comparison in
lib-src/emacsclient.c. It appears that the uid produced by geteuid()
isn't matching the uid for the server socket.

I first noticed the issue while trying to do a magit commit. But the
same error happens when trying to run emacsclient from the command line.
