          Issue ID: 17402
           Summary: dirEntries iterator crashes in conjunction with
                    readText
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: major
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: razvan.nitu1305 at gmail.com

The following code crashes:

auto dFiles = dirEntries("dmd/phobos/std/", "*.d", SpanMode.depth);
foreach (d; dFiles)
{
    string input = readText(d.name);
}

It seems that somehow readText breaks the dirEntries iterator. It works for the
first five files but then it crashes with the following error message:
