- Bill Egert pointed out (http://curl.haxx.se/bug/view.cgi?id=2671602) that

curl didn't use sprintf() in a way that is documented to work in POSIX but
  since we use our own printf() code (from libcurl) that shouldn't be a
  problem. Nonetheless I modified the code to not rely on such particular
  features and to not cause further raised eyebrowse with no good reason.
