The following C++ code segment is not working in debug mode build on HP-UNIX machine. It is not printing "Hello World" message on the screen. While it is working fine in release mode build.

==============================================

class KLogStreamBuf : public streambuf {
public:
...........
...........
void LogOn( ostream& l, const int ts = 1 ) {
FStreamBufsList.append( new KLogStreamBufs(l.rdbuf(), ts)); }
...........
...........
}


int main(int argc, char *argv[])
{
...........
...........

KLogStreamBuf DELogBuf1;

ostream DELog1( &DELogBuf1);

DELogBuf1.LogOn( cout);

DELog1<<"Hello World";

...........
...........
}

==============================================


For debug mode build I am using following compilation options

"/opt/aCC/bin/aCC -c -g +DA2.0N -w -AA -mt -N "


I would appreciate any help regarding it.

Regards,
