Reproducing the bug:


Consider the following code:
======== Original Version ========
#define Id_0

int GlobalVar_0 = 1;

int func_0() {
    int LocalVar_0 = 0; // To extract
    return GlobalVar_0;
}

int Function_0(int LocalVar_0) {
    return GlobalVar_0;
}
==================================

Now, let's the extract a function named "GlobalVar_0"
Applying the refactoring:
========== Refactored ============
#define Id_0

int GlobalVar_0 = 1;

int GlobalVar_0() {
    return 0;
}
int func_0() {
    int LocalVar_0 = GlobalVar_0();
    return GlobalVar_0;
}

int Function_0(int LocalVar_0) {
    return GlobalVar_0;
}
=================================

The tool shouldn't allow to apply invalid transformations like this. Notice that now the program has a compilation error. It would be good if it was possible to prevent incorrect extractions by checking if at least there's no name collisions.

Thanks in advance.
