--- Comment #3 from Jan Kokemüller <jan.kokemuel...@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=address").
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.
