Hi,
i see mentioned linker error on the current gcc-4.8.2 for i686-gnu-linux target
and somehow it works for x86_64-gnu-linux target.

MemoryOutStream is declared in the UnitTest++ as:
#include <sstream>
namespace UnitTest
{
class MemoryOutStream : public std::ostringstream
{
public:
MemoryOutStream() {}
char const* GetText() const;
private:
MemoryOutStream(MemoryOutStream const&);
void operator =(MemoryOutStream const&);
mutable std::string m_text;
};
}
