In the end, your intuition was correct (don't ignore the warnings unless you know why they're happening), and the warnings served their purpose (alerted you to a potential bug). They may not have explicitly come out and said what was wrong with the code, but they did point to the region of code where the Perl runtime was sensing a possible problem, and with a little digging you presumably have been able to fix the issue..
