Fix bad usage of sprintf() Usage of sprintf() to append to a string in the form of sprintf(buf, "%s...", buf...) is undefined, regardless whether it worked on a lot of older systems. It was always a bad idea and it now breaks on current glibc and gcc development environments. The moral: if any of your code uses sprintf() in a way similar to the above, fix it. It may not fail in a benign way.
