Forgive me for I know not much of the GCC internals (I use GCC, I don't develop it), but are you saying that any use of address-of on a variable kicks it out of contention for unused tracking? Even if it's not on a direct path (e.g., not always executed)? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42884
