On OpenBSD 7.6 there is a test failure:

FAIL: tests/ls/selinux-segfault

Find attached the log file.

To reproduce the issue, just run

$ src/ls -Z .
Segmentation fault (core dumped)

It crashes at strlen(), due to a NULL argument,
invoked from gobble_file (name = ".", type = arg_directory, inode = 0,
command_line_arg = true, dirname = NULL) at ls.c:3642,
invoked from ls.c:1812.

This reminds me the commit
https://git.savannah.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=915004f403cb25fadb207ddfdbe6a2f43bd44fac
that was supposed to fix the bug reported in
https://lists.gnu.org/archive/html/coreutils/2025-01/msg00051.html

Apparently this bug has reappeared, at least on OpenBSD.
