+       PR libstdc++/45628
+       * include/bits/fstream.tcc (basic_filebuf::underflow): Add state
+       transition to avoid modality requiring seekoff(0,ios::cur).
+       (basic_filebuf::pbackfail): Likewise.
+       (basic_filebuf::overflow): Likewise.
+       (basic_filebuf::_M_seek): Avoid minor unnecessary conversion.
+       (basic_filebuf::seekoff): Remove code to _M_get_ext_pos; make
+       (0, ios::cur) a special case preserving buffer contents.
+       (basic_filebuf::_M_get_ext_pos): New function to obtain status
+       about codecvt extern_t buffer for overflow and seekoff.
+       * include/std/fstream (basic_filebuf::_M_get_ext_pos): Likewise.
+       * config/abi/pre/gnu.ver: Export new symbols.
+       * testsuite/27_io/basic_filebuf/seekoff/char/45628-1.cc: New,
+       verifies that seekoff(0, ios::cur) preserves buffers.
+       * testsuite/27_io/basic_filebuf/seekoff/45628-2.cc: Likewise.
+       for codecvt case. More lenient as it may still flush put area.
+       * testsuite/27_io/basic_filebuf/seekoff/char/4.cc: Modify to
+       check that seekoff is not required between read and write.
+       * testsuite/27_io/basic_filebuf/seekoff/wchar_t/4.cc: Likewise.
+       * testsuite/27_io/basic_filebuf/sync/wchar_t/1.cc: Remove.
+       * testsuite/27_io/basic_filebuf/sync/wchar_t/1.cc: Likewise.
+       * testsuite/util/testsuite_character.h (codecvt::do_length): Comply
+       with 22.2.1.5.2/10 "Returns ... the LARGEST value in the range..."

+       * include/bits/functional_hash.h (__hash_base): Add.
+       (hash): Derive from __hash_base instead.
+       * include/debug/bitset (hash): Likewise.
+       * include/debug/vector (hash): Likewise.
+       * include/std/system_error (hash): Likewise.

+       * include/bits/stl_bvector.h (hash): Likewise.
+       * include/std/typeindex (hash): Do not derive from unary_function,
+       add result_type and argument_type typedefs; trim includes.
