When I create new project using "New File or Project..." -> "Non-Qt Project" -> "Plain C++ Project" it generates source file where main function defined as such:

int main() {
...
}

Environment command line arguments are missing. Correct definition should look like:

int main(int argc, char *argv[]) {
...
}

Such code breaks execution after return from main() to CRT and in some circumstances causes application to crash on exit (depends on platform, runtime version, compiler ABI, etc...)
