+ The type spec of the FormFunc argument to
+ sys:handle_debug/4 was erroneously pointing to dbg_fun().
+ This is now corrected and the new type is format_fun().</p>

+ Printing a term with io_lib:format and control sequence
+ w, precision P and field width F, where F&lt; P would
+ fail in one of the two following ways:</p>
+ <p>
+ 1) If P &lt; printed length of the term, an infinite loop
+ would be entered, consuming all available memory.</p>
+ <p>
+ 2) If P &gt;= printed length of the term, an exception
+ would be raised.</p>
+ <p>
+ These two problems are now corrected.</p>
