3935	stream<file_sink> does not throw an exception and not set fail/bad bits when file is wrong	zxspeccy.cpp@…	Jonathan Turkanis	"I'm trying to write some content to a new file using
boost::stream<file_sink> class.
Unfortunately errors/failures during opening the file are ignored by
boost library.

See attached test.cpp file for snippet.

Above program is started as non root user and have not access for file /wrong.txt

Result is:[[BR]]

Similar program using std::ofstream works as I expected:
- console prints: 1 0[[BR]]
- exception is thrown [[BR]]
