re PR libstdc++/9825 (filebuf::sputbackc breaks sbumpc)
2003-02-24 Paolo Carlini <pcarlini@unitus.it>
PR libstdc++/9825
* src/fstream.cc
(basic_filebuf<char/wchar_t>::_M_underflow_common): When
__bump is true (uflow), always increment the read pointer
(_M_in_cur) before returning successfully.
* testsuite/27_io/filebuf_virtuals.cc (test12): Add.
