https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219154 --- Comment #3 from Jan Kokem=C3=BCller <jan.kokemueller@gmail.com> --- I've added some tests to a local copy of 'contrib/netbsd-tests/lib/libc/gen/t_realpath.c' [1]. Would a new file in 'lib/libc/tests/gen' be a better place? realpath_buffer_overflow: This tests for the buffer overflow of the "left" array. But this test only fails with ASAN enabled ("-fsanitize=3Daddress"). realpath_empty_symlink: This tests for empty symlink behavior. Currently, "/tmp/empty_symlink/aaa" resolves to "/tmp/aaa", but the right behavior is to fail and return ENOENT. When ASAN is enabled this test crashes.
