1. Enable the clang code model.
2. Open a simple C++ file:

   #include <iostream>
   
   int main(int argc, char *argv[])
   {
       std::cou
   }
   

3. Place the cursor behind "cou" and press Ctrl+Space.
   It will be completed to "cout". This is correct.
4. Undo this change.
5. Remove a couple of characters from the #include line and press Ctrl+Space.
   It will be completed to #include <iostream>. This is correct.
6. Repeat step 3.
   It will be completed to "cout>". This is wrong. If it doesn't happen at first time, repeat it a couple of times.

Code completion should always add correct code. With Creator's built-in code model, this works correctly.
