check_nrpe = segfault when specifying a config file

[Worst45]

I installed the 'testing' version of nagios-nrpe-plugin in Debian 8 (v3.0.1-3 amd64), and the equivalent testing version of 'nagios-nrpe-server' on another host (also in v3.0.1-3 amd64) (to use the new SSL features and prevent old/insecure ciphers)

When I try to connect to the server with '-f' option (to specify SSL limitations), I get a segfault. This can be reproduced even when the config file is empty:

# /usr/lib/nagios/plugins/check_nrpe -H 192.168.x.y -f /etc/nagios3/nrpe.cfg
Erreur de segmentation       (Segmentation fault, in French)

No connection is made to the server (I activated debug output just to be sure, and no syslog event)

If I remove the '-f' flag, I get an SSL error that I will submit in another issue :)

Some details:

# /usr/lib/nagios/plugins/check_nrpe -V

How do you get the testing versions of packages?

Never mind, I figured it out. Checking now.
