Add this to your code: #include <string> Why? Probably a problem with typedefed, namespace qualified, forward template references involved in conversions during a throw operation ;-) Richard

Its debatable whether <stdexcept> should include the definition for std::string instead of declarations for std::string. In any case, it might be better to get into the habit of including <string> with <stdexcept> rather than adjusting the <stdexcept> lib. This will make sure nothing breaks if/when you upgrade stlport.

Or is it Stepanov's code, and who's who?
