The compiler cannot shield you from all programmer errors.

This would have helped early and is good practice:

char *months[12] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul",
"Aug" "Sep", "Oct", "Nov", "Dec"};

--> high probability warning

PS: I often assemble longer (format) strings from smaller ones
by means of macros, so if this ever to become a warning I'd
prefer to exclude macro-expanded occurrences.
