Internal error calling rtw_optimization info

When I try to generate code for a Simulink project I get this error:

Error calling generated SFunction, KalmanInTriplicate_sfun. 
Unexpected Standard exception from MEX file. 
What() is:Stateflow Internal Error: 
Internal error calling rtw_optimization info.

Does anyone know what this means? It is very vague to me.

Is there a way to fix the error?

Hi Fred, Were you able to get any resolution on the above issue. I am getting a similar kind of error during code generation of my Simulink project.

Any help on this is appreciated. Thanks..

Regards.
