We already have compiler errors (VJAR's) that point us to those places in which we have code that sets either <code>sequence_array</code> or <code>segment_array</code> to <code>Void</code>. Like this:
<code>
segment_array := Void
</code>
These instances need to be changed to attach an empty array, maybe like this:
<code>
create segment_array.make (1, 0)
</code>
Additionally, some postconditions which reference the implementation features <code>sequence_array</code> and/or <code>segment_array</code> would have to be changed. Looking at the postcondition clauses for <code>segment_start</code> we see that <code>segment_array</code> is expected (or not) to be <code>Void</code>:

As of EiffelStudio version 6.4, the majority of the libraries distributed with EiffelStudio are void-safe.
During a period of transition, there will be different Eiffel configuration files (.ecf's) for non-void-safe and void-safe projects. If you have set the '''Void-safe''' setting to check for void-safety, then when you add a library to your project in EiffelStudio, you will see the void-safe configurations by default. After the transition period, it is expected that there will be only one version of the configuration files for each library. The single configuration files will serve both non-void-safe and void-safe projects.
