Segmentation violation detected when stop time is infinite, in Simulink

I have written an C Mex function, in which i created a Shared Memory. I compiled it and i got ".mexw32" file. I am able to use that in an S-Function Model toolbox and Run it.

I wrote other file in Visual Studio, which can receive the data from this shared Memory. Even this is Compiled and built and it is Succeeded.

Now, i ran this Simulink model with finite Stop Time. This worked Properly without any fail.

But, i want the Process to Run Continuously, so, i set Stop Time as : Inf.

Now, i am facing an error. When i simulate the model with Infinite Stop Time, MATLAB crashes and i get an error:

Segmentation violation detected .

What could be the Problem?
