+ * PERL_DESTRUCT_LEVEL=2 GLIBCPP_FORCE_NEW=1 valgrind --leak-check=full /path/to/znc

+ * GLIBCPP_FORCE_NEW is an STL env flag to turn of mem pooling, and stops false alarms within stl
+ * PERL_DESTRUCT_LEVEL is a perl env flag to force the VM to cleanup, this also stops false alarms, but within perl
