ext/standard/tests/dir/closedir_variaton3.phpt
Something is broken in debug mode (has to be tested in normal mode). Doing readdir($fp); outputs some random buffer.
ext\standard\tests\file\is_file_variation4.phpt
/* Testing a file trailing slash */
var_dump(is_file("/is_file_variation4/is_file_variation4.tmp/"));
This test should return false for is_file or linux behavior has to be fixed.
