Another possibility is to use obscurer code that GCC can't figure out; that's what we did for the empty-string warning. I can't reproduce the problem on my platform (Fedora 19 with its GCC 4.8.2). Here's how I tried to reproduce it: ./gnulib-tool --create-testdir --dir foo xvasprintf cd foo ./configure CFLAGS='-Wformat -Werror=format-security -O2' make make check
