fuzz-ftp feeds its input to get_ftp_line() over a socketpair and runs each reply line through the PASV, EPSV, SIZE and MDTM parsers; the same bytes, read as a URL, go through the user, host and command splitters. ftp_parse_mdtm() loses its static so the harness can reach it. A 10-minute ASan+UBSan run (375k execs) found no crash. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Signed-off-by: Xavier Roche <roche@httrack.com>

The harness reads FTP replies with
get_ftp_line()over a socketpair and passes each one to the PASV, EPSV, SIZE and MDTM parsers. The same bytes also go through the URL splitters as an FTP link.ftp_parse_mdtm()is no longer static so the harness can call it, and a 10-minute ASan and UBSan run found no crash.
