Objective-C help needed with Bug#190497 - possible regression?

[Matthias Andree]

Greetings,

please bear with me if not using proper terms to describe the situation,
I am not an Objective-C programmer.

There are reports that openvpn-auth-ldap fails on FreeBSD 10, and
apparently also on 9, and I am unable to debug this.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=190497

I fixed WITH_DEBUG=yes and modernized -export-dynamic to
-Wl,-export-dynamic so that at least I get debug symbols in the output.
but if I try to debug the openvpn_plugin_v1_open function, and have a
breakpoint set on initWithConfigFile:, gdb 7.x (devel/gdb) just steps
over it, so I must assume the runtime is broken.

Note there are tons of complaints about classes not responding to +alloc
methods/messages.

The port builds - but does not install - a "testplugin" program in the
top-level $WRKSRC that I have been trying to use for debugging, so you
do not need to dig into openvpn configuration.  Just running
/usr/local/bin/gdb --args ./testplugin /path/to/auth-ldap.conf should
do, there is a sample file.

There is also an upstream bug, which has gone unattended so far.

Chances are that the problems have been introduced by switching to
clang, by using newer GCC, by using a newer obj standard library, or
thereabouts.

Any ideas how to fix this?

Best regards
