The deduplication code uses realpath to store the real path of a provided
configuration file. The code then tries to compare these paths but
accidentally only comparse only the first CONF_DIR_LEN (256) bytes of the
path.
The number of bytes must be set to the same length as the path size slot in
the normalized buffer.

systems")
