9718,boost::container::string assignment operator problem,Piotr Sulecki <piotr.sulecki@…>,Ion Gaztañaga,"The following code compiles with std::string, but fails to with boost::container::string. The error message is:
{{{
stringtest.cpp: In function ‘int main()’:
stringtest.cpp:21:5: error: no match for ‘operator=’ (operand types are ‘Msg’ and ‘const Msg’)
   y = x; // ok with std::string, compilation error with boost::container::string
     ^
stringtest.cpp:21:5: note: candidate is:
stringtest.cpp:7:8: note: Msg& Msg::operator=(Msg&)
 struct Msg
        ^
stringtest.cpp:7:8: note:   no known conversion for argument 1 from ‘const Msg’ to ‘Msg&’

}}}

...which suggests the assignment operator generated for Msg takes only a Msg reference, not a const one.

Boost 1.53.0 under Cygwin64, compiled using g++ (GCC) 4.8.1.
