Can't build simple project. Very strange errors

[Suliman via Digitalmars-d-learn]

I am getting very strange bug on very simple project. Here is 
sources http://rgho.st/7j5LQLZxb (blue button for downloading).

On: dub build I am getting error:

Unexpected OPTLINK Termination at EIP=0040F60A
EAX=03930000 EBX=00438C70 ECX=00000EE6 EDX=000002CE
ESI=00000104 EDI=03930468 EBP=0019FF38 ESP=0019FEF0
First=00402000

on: dub build --compiler=ldc2
It's buildable, but I am getting error on execution. The error 
says that file is corrupted.

If comment mysql driver. database.d:

import std.stdio;
import std.string;
import core.thread;
import ddb.postgres;
// import mysql; // <-- here
import vibe.d;
import config;

the project begin buildable with dmd and ldc2 and run ok.

I haven't seen such error before. I tried to clean

>link
OPTLINK (R) for Win32  Release 8.00.17

>DMD32 D Compiler v2.074.0
But I tested it on 2.073.0 too

Also I tried to cleanup folder:
AppData\Roaming\dub

but it did not help :(

Any ideas?
