[Boost-users] [Iostreams] Segmentation fault when stream is flushed or closed

Hello, I'm trying to open a boost::iostreams::stream in the constructor of a class and to close the stream in the destructor. This works fine but when I pass a reference to a std::stringstream in that same constructor I get a segmentation fault in the destructor when I flush or close the stream. This happens irrespective if the passed std::stringstream reference takes part in the boost::iostream::stream or not. I'm using gcc 4.6.3 with boost 1.53 on Linux x86_64. Below I provided a small example that exhibits this behaviour. Any ideas anyone? #include "test.h" int main(int argc, char **argv) { std::stringstream logStream; Test test(logStream); return 0; } where test.h contains: #include <fstream> #include <sstream> #include #include typedef boost::iostreams::tee_device TeeDevice; typedef boost::iostreams::stream<TeeDevice> TeeStream; class Test { public: Test(const std::stringstream& logStream) { std::ofstream dummyFileHandle("/dev/null", std::ios_base::out | std::ios_base::app); std::stringstream logStream2; TeeDevice myTee (logStream2, dummyFileHandle); m_out.open(myTee); } virtual ~Test() { if(m_out.is_open()) { m_out.flush(); m_out.close(); } }; protected: TeeStream m_out; };
