>Description:
	The makemandb program crashes on certain man pages.  In my
	case, the zabbix_agentd page from the pkgsrc-wip zabbix-agent
	package makes this happen (under the -v option):

Parsing: /usr/pkg/man/man8/zabbix_agentd.8
assertion "MAN_BLOCK == p->parent->type" failed: file "/usr/src/external/bsd/mdocml/lib/libmandoc/../../dist/man.c", line 212, function "man_node_append"
Abort (core dumped)

	The same happens if you do "man" on that manual page.
	However, if you do "nroff -man" on the manpage, it formats
	~ok.  The manpage doesn't use the new man page macros.

	This has the slightly nasty side effect that "man -k" on this
	machine is useless, as any lookup results in:

apropos: Unable to query schema version: disk I/O error

	(I thought that error code / message was reserved for actual
	hard IO failures, which this isn't an instance of.)


>How-To-Repeat:
	Install the pkgsrc-wip zabbix-agent package, watch either "man
	zabbix_agentd" or "makemandb -v" crash.

>Fix:
	There's quite a few updates to man/mkmandb in newer NetBSD
	code, but it appears to drag along also an update of mdocml
	and sqlite...

	However, with a wholesale upgrade to HEAD of all those 4
	components, makemandb no longer crashes, and "man
	zabbix_agentd" works as expected.
	Is this too invasive to contemplate pulling up to netbsd-6?
	Or does there exist a "point fix" for this problem?

 That's a sqlite error message, which is probably a sqlite bug; it
 should probably be producing SQLITE_CORRUPT instead of
 SQLITE_IOERROR.

 But that's a side issue; crashing shouldn't corrupt the database.
 That's part of the point of using database software. This suggests
 that makemandb and/or apropos isn't using sqlite correctly.

 Dunno. Updating sqlite is probably a fine idea, but by itself it's
 unlikely to fix the problem.

 This is effectively a duplicate of PR bin/46178.

 Yes, I agree, it is.
