Upgrading libgcc didn't reexec systemd

[matthew-cline]

After upgraded the libgcc package, using fuser showed that systemd (PID 1) wasn't using the new shared library, and fuser only changed to showing it using the new library after manually doing systemctl daemon-reexec.

System/setup:

• Fedora 33
• needrestart 3.5-3
• systemd 246.13-1
• dnf 4.6.1-1
• python3-libdnf 0.60.0-1

Could you please provide the output of needrestart -v ?

needrestart -v output:

Running kernel seems to be up-to-date.

The processor microcode seems to be up-to-date.

Restarting services...

Service restarts being deferred:
 systemctl restart user@1000.service

No containers need to be restarted.

No user sessions are running outdated binaries.

Could you please add the output your fuser call (including command parameters) and /proc/1/maps? I would not expect that systemd is linked dynamic against libgcc.
