Hi Deepak, can you please attach all the relevant files so someone can reproduce the problem? We'd need all the files that were produced in the "codegen" folder (easiest if you just zip the codegen folder). If you have created a Visual Studio project, please attach it to.
I see you attached processWGMM.txt (a C file) and main.txt (a C file) but no headers and no other files.
Or, you can debug the issue yourself by doing a debug build in Visual Studio, and running the application under debugger, then it'll stop at the line where the exception occurs, and you should be able to see where and why it happens.
hth,
Denis
