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).

#include
using namespace std;
int main()
{
boost::asio::streambuf Stream;
// Put 4 bytes into the streambuf...
int SetValue = 0xaabbccdd;
Stream.sputn(reinterpret_cast(&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(&GetValue), sizeof(GetValue));
cout << Stream.size() << endl; // should output 0
return 0;
}
