PR libstdc++/6746 * include/bits/fstream.tcc (filebuf::open): Set input pointers. * config/io/basic_file_stdio.cc (__basic_file::_M_open_mode): Set __p_mode as well. (__basic_file::open): Set to non-block for input. * testsuite/27_io/istream_unformatted.cc (test12): Add. (test13): Same. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@59030 138bc75d-0d04-0410-961f-82ee72b054a4
