+ <p>The compiler would translate binary comprehensions
+ containing tail segments in a way that would would
+ confuse Dialyzer. For instance:</p>
+ <p><c>[42 || &lt;&lt;_:8/integer, _/bits&gt;&gt; &lt;=
+ Bits]</c></p>
+ <p>
+ would produce a Dialyzer warning.</p>

+ Code such as <c>foo(A) -&gt; &lt;&lt;A:0&gt;&gt;</c>
+ would crash the compiler.</p>

+ <p>
+ The compiler could fail with an internal error when
+ variables were exported from a receive block but the
+ return value of the receive block were not used. (Thanks
+ to Jim Engquist for reporting this error.)</p>
