Now, I coded my MIP problem in C++ with using concert technology with CPLEX.
I have a serious problem and I could not find the reason of my error.
The error is "stack over flow". When I solved my problem with some constraints, I have the results, but when I added another constraints, I saw this error. Another weird point about this error is when I comment one constraint and add another one, the code worked properly. It is really strange.

can anybody help me?

I don't think that CPLEX is likely to be the culprit for a stack overflow. A stack overflow usually only happens if you use recursive functions or allocate very big data on the stack. Do you do any of this?

Could you provide a backtrace for that stack overflow exception/error? What is the function that triggers it?

the problem was in c++, and the error was "stack overflow". I checked several times my code, and it was ok. I found the problem was the stack size in visual studio.

 I increased it and now it works properly.

I changed the stack reverse size in the "linker" setting of visual studio, and change it by entering the stack size in byte.
