------------------------------------+---------------------------------------
 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]]
 mariusz_at_ppbw:~/boost-1.42$ ./test [[BR]]
 boost ver:1_42
 [[BR]]
 0 0[[BR]]
 nothing thrown[[BR]]

 mariusz_at_ppbw:~/boost-1.42$ ls /[[BR]]
 bin    dev   initrd.img      lost+found  opt   sbin  tmp  vmlinuz[[BR]]
 boot   etc   initrd.img.old  media       proc  srv   usr
 vmlinuz.old[[BR]]
 cdrom  home  lib             mnt         root  sys   var[[BR]]

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

 I made tests using:[[BR]]

 g++ (Debian 4.3.2-1.1) 4.3.2[[BR]]
