useful for you to send the same information to the maintainer who is,
presumably, still interested in fixing this bug.
Just to clarify things, yes, I do recognise there is an issue here and
yes, I am still working to find a resolution. My reluctance in
approving the patch in ports/131993 simply boils down to the fact I am
unable to even reproduce the issue, and believe me, I have tried on
many, many systems.
The issue seems to be the passing of the embedding variable to
Perl_sys_init3 (aka PERL_SYS_INIT3). The second argument to this
function takes a char *** which init_embedded_perl() attempts to pass
to it as a pointer to a char **, err... This does generate a warning
during compilation but as to why the embedded Perl functionality still
works on my systems without faulting is beyond me.
Sebastian's patch will resolve the problem, and with some
modifications and additional checks and warnings, I have a patch which
now needs some testing. Grab it from the URL below, dumping it in /usr/
ports/net-mgmt/nagios/files.

I've tested it as much as I can and don't believe it introduces a
regression on non-faulting systems so if it solves the issue for users
with faulting nagios binaries, then I will bundle it up and have it
committed.
Is the benefit to the embedded perl option worth the occasional bug
report? Is it possible to remove this option from the port?
I believe so, systems with many Perl based probes do benefit from
starting just one instance of the interpreter.
Jarrod.
