This seems to be a simple problem with initialisation of variables on
some platforms or under certain optimisations. I ran across the same
problem recently on Solaris and the patch at the bottom of
http://www.nagiosexchange.org/nagiosplug-devel.31.0.html?&tx_maillisttof
aq_pi1%5Bmode%5D=1&tx_maillisttofaq_pi1%5BshowUid%5D=17265 fixed it for
me. Here it is.

Presumably a fix of some kind is in the current CVS version.
