Hi!

I got a test case which shows the error.

http://svn.boost.org/trac/boost/browser/sandbox-branches/birbacher/tmp_iostreams/libs/iostreams/test/error_test.cpp?rev=39180
(notice: new branch)

The new test case does (test_write_close):
1. crete a stream in "open" state
2. try writing to it (streambuf does not yet throw)
3. close the stream !!! (stream buffer should be flushed and streambuf
should throw now and cause badbit to be set)
4. test for errors: NONE?!

Results of the test suite:

This is clearly not the behaviour which I'd expect.
