Suppose I have this function:

std::string Func1(std::string myString)
{
   //do some string processing 
   std::string newString = Func2(myString)
   return newString;  
}

How do I set a conditional break when newString has a specific value? (without changing the source)

Setting the condition newString == "my value" didn't work. The breakpoints were disabled with an error overloaded operator not found.
