structure tracking. Now when the new streambuf position is exactly at the end of the previous streambuf, we only fuzz the streambuf if new data is available (i.e. when streambuf_count != 0); otherwise, it just means that we’re at the end of the file, waiting for new read orders.
About zzuf: zzuf is a transparent application input fuzzer. It works by intercepting file operations and changing random bits in the program's input. zzuf's behaviour is deterministic, making it easy to reproduce bugs. For instructions and examples on how to use zzuf, see the manual page and the website at <http://caca.zoy.org/wiki/zzuf>.
