I've experienced problems using asio::streambuf and am hoping someone can tell me if I'm using the class incorrectly. When I run this example code it segfaults. Why? To make things more confusing, this code works on Windows (Visual Studio 2008), but does not work on Linux (with gcc 4.4.1). -- Dylan #include <boost/asio.hpp> using namespace std; int main() { boost::asio::streambuf Stream; // Put 4 bytes into the streambuf... int SetValue = 0xaabbccdd; Stream.sputn(reinterpret_cast<const char*>(&SetValue), sizeof(SetValue)); // Consume 3 of the bytes... Stream.consume(3); cout << Stream.size() << endl; // should output 1 // Get the last byte... char GetValue; // -------------------------- The next line segfaults the program -------------------------- Stream.sgetn(reinterpret_cast<char*>(&GetValue), sizeof(GetValue)); cout << Stream.size() << endl; // should output 0 return 0; }
