New revision: 318450
URL: https://svnweb.freebsd.org/changeset/base/318450
Log:
Add tests for some cases in r318298.
The first test triggers the out of bounds read of the 'left' array. It
only fails when realpath.c is compiled with '-fsanitize=address'.
The other test checks for ENOENT when running into an empty
symlink. This matches NetBSD's realpath(3) semantics. Previously,
empty symlinks were treated like ".".
