I tried that on Fedora 27, which has GCC 7.2.1 20170915 (Red Hat 7.2.1-2), and 
got some of the warnings that you mention. I suggest using -O2 instead, as this 
is the default optimization level and it made the warnings go away for me. I'd 
rather not contort the code to pacify false alarms for every possible 
combination of GCC options, as it's too much work for too little benefit.
