Error with Simulink.AliasType in xPC target

Hello.

I'm trying to run a model on a xPC target machine.

However, there is program error with Alias Type.

There is an warning after building the model If i include alias data type in a model.

*Warning: An ERT or ERT derived target is required to preserve the names of alias data types in the generated code. Reverting to builtin types during code generation. *

After I ignore the warnning and click the button 'connect to target', the Simulink/Matlab program shut down.

Is this situation is software bug?

or is the Alias type cannot be used with Simulink.AliasType?

If MATLAB crashed, I would recommend that you send your model with reproduction steps to MathWorks Support so they can determine if this is a bug and suggest a solution.
