This code:

import std.file;
void main()
{
    string[] dirs;
    foreach (string dir; dirEntries(r"C:\", SpanMode.shallow))
    {
        if (dir.isDir)
            dirs ~= dir;
    }
}


Compiled via DMD 2.055 commit cfab198ee186f6e69c364aaf4206434220d83204 (Aug
15), enters an infinite loop at runtime where exceptions are kept throwing:

=== Bypassed ===
std.file.FileException at std\file.d(1156): C:\pagefile.sys: The process cannot
access the file because it is being used by
another process.

It seems after it tries to open the protected pagefile.sys it keeps rethrowing
exceptions and not exiting the foreach loop. It doesn't stop at all, just keeps
rethrowing.
