rsync 2.6.1cvs dumps core when preserve_hard_links and backup

[Shinichi Maruyama]

	I tried rsync 2.6.1cvs on my FreeBSD 4.X boxes.
	It dumps core when preserve_hard_links and backup.
And SUPPORT_HARD_LINKS is true.

	rsync -avH --delete --backup --backup-dir=/some/backup/dir \
		srchost::dir/ dir/

	The core says...

  flags = 0 '\000'}
------------------------------------------------------------------------

	In file backup.c.

266             if (!kept && preserve_hard_links && file->link_u.links
267                 && hlink_list[file->F_HLINDEX] != file) {
268                     if (verbose > 1)
269                             rprintf(FINFO, "%s is a hard link\n", f_name(file));
270             }

	file->link_u.links (and also file->F_HLINDEX) has some values,
but no meanings because it's only an union with file->link_u.idev.
	It may be

             if (!kept && preserve_hard_links && file->u.link) {

or some ?

-- 
Yes, I'm in panic.
