           Summary: dirEntries fails to generate file list when compiled
                    with -inline
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: callumenator gmail.com

This code:

auto dFiles = dirEntries("testimages/","*.png",SpanMode.shallow);
foreach(d; dFiles)
  writeln(d.name);

should generate a list of four filenames, however when compiled with -inline it
generates none. In release mode with -O (not using -inline) it works fine. 

Windows 7 x64 using DMD32 2.059 (same thing happened with 2.058).

Imperfect test case

Imperfect test case which doesn't show the precise described behaviour, but
nevertheless fails to correctly implement the required dirEntries filter, so
may be useful in tracking down bug.

Sorry, the error in the above example is from inappropriate use of takeExactly.
:-(  dirEntries does indeed return an empty list, and when the correct subdir
is put in place, it returns the list of files.  So, it's not a minimal example
of the bug or even related.

However, I _am_ still experiencing this problem of an empty list due to a
filter which _should_ return a non-empty list of files, and indeed does when
compiled with ldmd2 -- but fails when compiled with latest from-GitHub dmd:

    auto fileList = dirEntries(testSetDir, "*.txt", SpanMode.shallow);
    foreach(DirEntry e; fileList)
    {
        ...
    }

If I remove the "*.txt" filter (there are only .txt files in the directory) the
fileList is correctly populated.

(In reply to comment #2)

To clarify: it fails when compiled with dmd -inline, but works correctly when
-inline is omitted.  With ldmd2 it works with or without the -inline flag.

Full test case:

---

import std.file;

void main()
{
    mkdir("test8250");
    scope(exit) rmdirRecurse("test8250");

    write("test8250/a.txt", "test");

    bool found;
    auto dFiles = dirEntries("test8250/", "*.txt", SpanMode.shallow);
    foreach (d; dFiles)
        if (d.name == "test8250/a.txt")
            found = true;

    assert(found, "Can't find a.txt");
}

---

Succeeds with: dmd -run bug8250.d 
Fails    with: dmd -inline -run bug8250.d 

Will attempt to reduce Phobos dependency and refile.
