Reproducing the bug:


Consider the following code:
======== Original Version ========
int main(int a, char** argv) {
    int b = 0; // Variable to be renamed
    return b;
}
==================================

The refactoring tool is allowing to rename the variable "b" to an invalid identifier (in the following case, a pointer):

========== Refactored ===========
int main(int a, char** argv) {
    int *b = 0; // Invalid rename!
    return *b;
}
=================================

Notice that when compiling the resulting program (Refactored), the compiler issues a warning (since I'm returning a pointer instead of an integer). When attempting to execute the refactored version, a Segmentation Fault is thrown.

Maybe it would be better to check the rules of a well-formed identifier before applying the transformation to avoid this kind of problem.


Thanks in advance.
