           Summary: Clang should warn on use of a local variable in its
                    own initializer
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

-Wuninitialized should complain about this:
void f() {
  int i = i;
}

A more realistic example of how this could happen:
void f(int* encoded_result) {
 // Note the typo below, it should be
 // bool encode_result = (encoded_result != NULL);
 bool encode_result = (encode_result != NULL);
 if (encode_result) *encoded_result = 42;
}
