7698,Boost directory iterator constructor crashes when folder gives input/output error,cpl,Beman Dawes,"By using the directory iterator on a non accessible forlder under Linux, the following crash happens:

A sample code that generates the crash is the following:

boost::system::error_code ec;
boost::filesystem3::directory_iterator itr(dir_path, ec);

Where the dir_path is a folder that is not accessible. Using the ls command from terminal on the same folder returns:

input/output error

If the error returned is permission denied, everything works fine. I triggered the input/output error using the curlftpfs library which mounts a ftp as a folder on the system. The permission denied error can be generated on the same folder using nfs share.",Bugs,new,To Be Determined,filesystem,Boost 1.47.0,Problem,,,
