Oh, you are entirely right. I completely missed that gcc had this check. All of my test cases are covered by gcc's check, and gcc's check is a bit smarter than mine (`sprintf(stp->buf, "%s", st1.buf)` is caught by gcc, but not my check).

Is this still worth adding here? I didn't see an equivalent in clang's -Wall.
