Paste the following code at the bottom of phobos/unittest.d. This simply
increases the size of unittest executable.
--------------------
unittest
{
    struct K(Q...)
    {
        static if (Q.length < 5) static K!(Q, int) next;
        Q q;
    }
    static K!byte a1;
    static K!short a2;
    static K!int a3;
    static K!long a4;
    static K!ubyte a5;
    static K!ushort a6;
    static K!uint a7;
    static K!ulong a8;
    static K!float a9;
    static K!double a10;
    static K!real a11;
    static K!char a12;
    static K!wchar a13;
    static K!dchar a14;
}
--------------------

Then, run the phobos unittest on Windows. It will crash.
--------------------
>make -f win32.mak unittest
...
unittest
object.Error: Access Violation
--------------------

Access violation seems to start happening when the size of executable exceeds
some critical point. Sometimes the AV didn't occur, and alternatively the test
showed weird behavior - such as infinitely failing unittests or broken output.

See this message and follow ups.
