(all below for sstream released with gcc < 3)

Not really, but I belive it is the same as I have seen ealier with
stringstream:

stringstream used for input _and_ output at the same time does not
behave properly.

other than that istringstream and ostringstream work just dandy.

From the lyx code I have this snippet:

                       // Now we should have the whole layout in ss
                        // we should now be able to give this to the
                        // caption inset.
                        ss << "\\end_inset\n";
 
                        // This seems like a bug in stringstream.
                        // We really should be able to use ss
                        // directly. (Lgb)
                        istringstream is(ss.str());

ditto here.
