Is that the complete definition?

Google tells me that this "Quelltyp konnte von keinem Konstruktor 
angenommen werden, oder die Ueberladungsaufloesung des Konstruktors ist 
mehrdeutig"?" translates to "Source type could be accepted by no 
constructor, or the dissolution of overloading of the constructor is 
ambiguous." From this, I would guess either that the invalid_argument 
class has another constructor that you didn't show that is making the 
conversion ambiguous, or that the string class either has no constructor 
that takes a single char* argument, or else that constructor is marked 
"explicit", or else there are multiple constructors and the choice 
between them is ambiguous.
