As was pointed out below the CString doesn't support instance method string:. Crashing this in a debugger should give you call stack so you can trace who is doing the calling. You should also have a crash log that can be symbolized.
But, if this is your code run it in the debugger and have it crash. Use the call stack to see who is making this call.
