>Description:
I'm packaging up zabbix 2.4.2 (so far in pkgsrc-wip, yet to be
committed at this stage). It has a man page, zabbix_agentd,
where when it's installed, "man zabbix_agentd" yeilds an empty
man page and an error message which says
floke: {17} man zabbix_agentd
man: Formatting manual page...
assertion "MAN_BLOCK == p->parent->type" failed: file "/usr/src/external/bsd/mdocml/lib/libmandoc/../../dist/man.c", line 212, function "man_node_append"
[1] Abort trap /usr/bin/mandoc ...
floke: {18}
Doing the more traditional
% nroff -mandoc <manpage> | less -s
gives a perfectly readable man page.
I would therefore characterize this as "lack of robustness".
Likewise, makemandb crashes if such a man page is installed.
