Bug #73488 [NEW]: DirectoryIterator::isDir() strange behavior

From: stan dot wanderer at gmail dot com Operating system: ubuntu 16.04.1 lts x64 PHP version: 7.0.13 Package: *Directory/Filesystem functions Bug Type: Bug Bug description:DirectoryIterator::isDir() strange behavior Description: ------------ hello, I've noticed that the DirectoryIterator object (as I know extended from SplFileInfo) has strange behavior of method isDir() - random boolean result on real directories. I've tried to run my tests on different environments (the same results): Ubuntu 16.04.1 LTS (GNU/Linux 4.4.0-45-generic x86_64) # php -v PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies with Zend OPcache v7.0.8-0ubuntu0.16.04.3, Copyright (c) 1999-2016, by Zend Technologies Ubuntu 14.04.5 LTS (GNU/Linux 4.8.3-x86_64-linode76 x86_64) # php -v PHP 5.5.9-1ubuntu4.19 (cli) (built: Jul 28 2016 19:31:33) Copyright (c) 1997-2014 The PHP Group Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies with Zend OPcache v7.0.3, Copyright (c) 1999-2014, by Zend Technologies Maybe it is not a bug, but I cannot find any information about this issue.
