Win32: How to get the stack trace when compiling with a windows subsystem?

When you compile with -L/SUBSYSTEM:WINDOWS you're essentially building
an app without a console, so if you want to print out messages you'd
have to log them to a file. For example:

-----
import core.sys.windows.windows;
import std.stdio;

extern(Windows) HWND GetConsoleWindow();

void main()
{
    if (!GetConsoleWindow())
    {
        stdout.open(r".\stdout.log", "w");
        stderr.open(r".\stderr.log", "w");
    }

    try
    {
        realMain();
    }
    catch (Throwable thr)
    {
        stderr.writeln(thr.msg);
        throw thr;
    }
}

void realMain()
{
    assert(0);
}
-----

Compilable and runnable with:

dmd -g -L/SUBSYSTEM:WINDOWS:5.01 -run test.d

This will write the exception message to a log file, however I'd also
like to retrieve the stack trace to log that as well. For example
here's the output in a regular console app (without the windows
subsystem):

core.exception.AssertError at test(29): Assertion failure
----------------
0x0041D93B in onAssertError
0x004020DD in void test.realMain() at C:\dev\code\d_code\test.d(30)
0x0040208B in _Dmain at C:\dev\code\d_code\test.d(18)
0x00417BE8 in extern (C) int rt.dmain2._d_run_main(int, char**, extern (C
) int function(char[][])*).void runMain()
0x00417C78 in extern (C) int rt.dmain2._d_run_main(int, char**, extern (C
) int function(char[][])*).void runAll()
0x00417555 in _d_run_main
0x00408690 in main
0x0042DD29 in mainCRTStartup
0x774F33CA in BaseThreadInitThunk
0x77D09ED2 in RtlInitializeExceptionChain
0x77D09EA5 in RtlInitializeExceptionChain

I'd like to log this out when building with a windows subsystem. Is
there any way to do that?
