Matlab has encountered an internal problem and needs to close

Good afternoon! I create s-function on C from an example csfunc.c. I create mex. Also I try to connect it in simulink the block s-function. But there is an error "Matlab has encountered an internal problem and needs to close" and closes matlab. Somebody had such error? Or it is better to address in technical support...

Thanks

Did you modify the S-function? If yes, it is likely that your code is causing a segmentation violation causing MATLAB to shut down. Please read How Do I Debug C MEX S-Functions for information on debugging your S-function.
