strncat is not the maximum length of the destination string, but of the SOURCE string, thus strncat (dest, src, sizeof (dest)) is incorrect. It should be strncat (dest, src, sizeof (text) - strlen (dest)). Even then, no terminating nul will be written if src is too long, but at least it won't crash the stack:)
