DLL with D (FreeLibrary problem)

[Exec]

Hello everybody.
I'm trying to write a DLL in D. Everything is actually working fine, until I reach FreeLibrary,
which terminates the test program (written in D) with code 0x1. DllMain is called correctly,
and seems to run through. But I never reach the lines after the FreeLib call.

DLL: http://pastie.org/private/edvmql0g768blgx81nh14g
Def: http://pastie.org/private/lrmuzenou8clmjppqqj9gw
Program: http://pastie.org/private/2yvvjymgq5u50mtgyqjr0a
Output: http://pastie.org/private/kktyjs6hnbjohgwzwzqsjq

When I write the same program in C++, to test the DLL, I have a similar problem,
although the program doesn't crash. Nothing is printed, after FreeLib, but it's still
waiting for the input at getch().

I'm still new to DLLs, or rather system programming in general,
and actually have near to no idea, what could be going wrong here.
