Description
Discovered while trying to write a new su implementation (and confimed present in the existing coreutils su and login.)
If you are in a Terminal session, and attempt to su or login to another (non-root) user, then the login process exits with "Killed (by death)" aka SIGKILL. I traced this to the execv call where it starts the shell (https://github.com/haiku/haiku/blob/master/src/bin/multiuser/login.cpp#L282).
This is hrev51234.

I'd add a couple of dprintf() calls to exec_team(), and see where this leads to.
If the team is killed, it probably happens due to not being able to fully initialize the new executable/environment.

Works now. Must've been caused by the bad umask.
Note:

Oh, sorry, forgot to mention: login/su to root (on root) works OK. login/su to another user (meaning, setuid/setgid are run) is what causes a problem here.
