stringstream bug in VC9? "Cannot access private member"

Question

std::string str;
std::stringstream strm(str);

I get this error:

Error 11 error C2248: 'std::basic_ios<_Elem,_Traits>::basic_ios' : cannot access private member declared in class 'std::basic_ios<_Elem,_Traits>' c:\program files\microsoft visual studio 9.0\vc\include\sstream 517

If I use istringstream, same happens.

Compiler: Visual C++ 2008.

Answer 1

#include <string>
#include <sstream>

int main( int argc, char *argv[] ) {
    std::string str;
    std::stringstream strm( str );

    return 0;
}

Compiles fine with no errors/warnings for me in VS 2008. Can you post the full code?

Answer 2

Sounds like you are trying to copy a stream. This is not possible as the copy constructors are private.
