That seems nearly impossible. The warning is emitted in the FE, and this would
require inlining and/or constant propagation into function calls. Not likely to
ever happen in GCC. You need something like http://clang-analyzer.llvm.org/ or
http://cppcheck.sourceforge.net/. Better report a bug to them.
