while running the matlab coder , during the run-time checks while the matlab runs with its generated mex, it crashes leaving no crash report.
I tried to comment\uncomment line codes to see if there's a problematic line but didn't find any.The only thing that affects is the total amount of code.
Could this be a memory issue with the mex? how can I identify and solve this

You can debug the generated mex and identify the problem site. To debug generated MEX code, just pass the -g option to codegen and that will compile a debug MEX file. You can then debug that MEX code by following the same process you'd use for debugging hand-written MEX files:
In short, you compile and run the MEX in MATLAB and attach Visual Studio to MATLAB, stopping when the MEX code is executed.
Note that the -g option is the same as the Coder config setting EnableDebugging:
