State-Changed-Why:
In a few days a new snapshot of libstdc++-v3 will be
released, a version of which (named libstdc++-v3.0.95-gcc-3.0.3.tar.gz)
can be straightforwardly plugged in in the gcc3.0.3
distribution. Most certainly it will solve your problem.
Thanks,
Paolo.

>Description:
After inserting a pointer to a streambuf into an output stream,
the eof bit is set in the output stream and nothing else can
be inserted (unless clear() is called on the stream first).
I think the problem is caused by the function __copy_streambufs
which wrongly sets the eof bit in the output stream.
>How-To-Repeat:
Compile and run this test program. Usage: program infile outfile.
The first argument must be a readable file.
It should copy one file to another and append "Hello\n" to the output file.
With g++ 3.0.3 the "Hello\n" is not written to the output file, and good() returns false.
It works correctly with several other compilers.
/********** Start of test program ***************/
#include <fstream>

using namespace std;
int main(int argc, char** argv)
{
if (argc != 3)
return 1;
ifstream i(argv[1]);
ofstream o(argv[2]);
o << i.rdbuf();
cout << o.good() << endl;
o << "Hello\n";
return 0;
}
