Re: [Boost-users] [exception] What's wrong withboost::get_error_info?

Long shot, but it looks like you have ABI conflict of some sort. Could you post a simple, complete program that demonstrates your problems?

Here is the complete sourcecode of a Win32 console application that reproduces my problem. And shame on me, I forgot to mention that my application as well as the Boost libraries uses STLport version 5.0.2

#define WIN32_LEAN_AND_MEAN // Exclude rarely-used stuff from Windows headers #include #include #include

class MyBoostException : public boost::exception { public: MyBoostException() { /*do nothing*/ }; virtual ~MyBoostException() { /*do nothing*/ }; };

void DoSomething() { throw MyBoostException() << boost::throw_file( _T(__FILE__) ) << boost::throw_line( __LINE__ ) << boost::throw_function( _T("DoSomething()") ); }

int _tmain( int argc, _TCHAR* argv[] ) { try { DoSomething(); } catch( MyBoostException& ex ) {

boost::shared_ptr<const int> pLine = boost::get_error_infoboost::throw_line(ex);

boost::shared_ptr pMethod = boost::get_error_infoboost::throw_function(ex); const char* sMethod = *pMethod;

boost::shared_ptr pFile = boost::get_error_infoboost::throw_file(ex); const char* sFile= *pFile;

std::string info = boost::diagnostic_information( ex ); const char* sString = info.c_str();

} return 0; }

I am puzzled, but here is another guess. Boost::throw_line, boost::throw_function and boost::throw_file have special handling in Boost Exception; adding them to exceptions does not use anything from STL. So here is something to try: print *pLine, sMethod and sFile directly. If you get correct strings, then the problem could be in some interference between STLport and std::ostringstream. Step into boost::diagnostic_information and see what is passed into std::ostringstream's operator<<. If the data entering it is good but the output from .str() is bad, it's definitely an issue with STLport's installation.
