Description of problem:
I'm using dnsmasq to provide local DNS caching with NetworkManager so NM is responsible for starting and managing dnsmasq. This is an IPv4-only system.

These are the related configuration files in the setup:

1. cat /etc/resolv.conf
   nameserver 127.0.0.1
   search example.com
   options edns0 no-aaaa trust-ad
2. cat /etc/NetworkManager/conf.d/50-dns.conf
   [main]
   dns=dnsmasq
3. cat /etc/NetworkManager/conf.d/99-rc-manager.conf
   [main]
   rc-manager=unmanaged
4. cat /etc/NetworkManager/dnsmasq.d/zz-local.conf
   addn-hosts=/etc/hosts
   domain-needed
   bogus-priv
   local=/example.com/
   local-ttl=10
   min-cache-ttl=10
   neg-ttl=10

When booting up the system or restarting NM I see new core files appearing:

1. file /var/lib/systemd/coredump/core.5835
   /var/lib/systemd/coredump/core.5835: ELF 64-bit LSB core file, x86-64, version 1 (SYSV), SVR4-style, from '/usr/sbin/dnsmasq --no-resolv --keep-in-foreground --no-hosts --bind-interfaces', real uid: 0, effective uid: 0, real gid: 0, effective gid: 0, execfn: '/usr/sbin/dnsmasq', platform: 'x86_64'

I'm not sure if this is the same issue as bug 2182342 but filing just in case and will attach a core dump. Thanks.

Version-Release number of selected component (if applicable):
dnsmasq-2.85-5.el9.x86_64
