Reproducing the bug:


Consider the following code:
======== Original Version ========
#define A // Macro to be renamed
int main(int argc, char** argv) {
    int a;
#ifdef A
    a = 1;
#endif
#ifdef B
    a = 2;
#endif
    return a;
}
==================================

Now, let's rename the macro A to "B".
Applying the refactoring:
========== Refactored ============
#define B
int main(int argc, char** argv) {
    int a;
#ifdef B
    a = 1;
#endif
#ifdef B
    a = 2;
#endif
    return a;
}
=================================

The refactoring tool didn't check for existing references. In this case, B should not be permitted for a renaming because of the existing #ifdef B.


Thanks in advance.
