    bug_occurred: a place where we assumed that "buf" was still a buffer
    
    In 9c132a5f9e87a2cd0f we replaced "buf" with a pointer and replaced
    one instance of snprintf with asprintf -- but there was still one
    snprintf left over, being crashy.
    
    Fixes bug 29967; bug not in any released Tor. This is CID 1444262.
