I have compiled the latest version from source code
The program that virtualizes outputs only std::cout << "Hello world" << std:endl;
And this always happens with any program, either the error is in the ValueTracking.cpp or Semantics.cpp

Thank you for creating the issue!

This is caused because cout is an object with its own vtable and since that function is not really an import and we dont symbolize that function, Mergen believes the function doesnt exist and we are trying to call an invalid function.

This should be fixed once we integrate a more traditional lifter that will allow the user to symbolize or inline whatever function user wants. Obviously that will have its own issues like you might need to use other tools for control flow but it will be more accurate for cases like these
