lsof 4.99.4+dfsg-2 seems to be affected
by the upstream bug https://github.com/lsof-org/lsof/issues/335
which is fixed in 4.99.6 upstream.

lsof 4.93.2+dfsg-1.1 from Debian 12 does not seem to be affected.

For certain NFS mounts we have,

sudo lsof -e /mnt/nfs/secondary-scratch/ +L1

works

sudo lsof -e /mnt/nfs/secondary-maps/ +L1

crashes with the following backtrace:
