[Pkg-nagios-devel] Bug#884076: nagios-plugins-standard: check_mysql segfaults with --extra-opts

[Joonas Kylmälä]

Package: monitoring-plugins-standard
Version: 2.2-3
Severity: normal

Dear Maintainer,

I ran the command "/usr/lib/nagios/plugins/check_mysql --extra-opts" and
it gave me the following output: "Segmentation fault".

I would have expected it to give the same output as running the command
like this:

$ /usr/lib/nagios/plugins/check_mysql
--extra-opts=check_mysql@/etc/monitoring-plugins.ini
