I'm still investigating why it crashes when using

Looks like a revenant of
https://d.puremagic.com/issues/show_bug.cgi?id=9729.
The problem is that nobody sets ebx before calling the
interface thunk,
therefor resolving the @PLT entry fails.
_TMP5 LABEL NEAR
sub eax, 8 ; 0078
_ 83.
E8, 08
jmp _D6plugin6Plugin12saySomethingMFZAya ; 007B
_ E9,
FFFFFFFC(PLT r)
I prepared a fix here
(https://github.com/MartinNowak/dmd/tree/thunkEBX)
but it needs more work. Currently it violates the platform ABI
because the interface thunk destroys EBX.
Thanks Martin - it's good to have you involved. I'd got as far as
dissasembling it and stepping single instructions in GDB while
looking at that, so I could have told you where it crashed, but
had no idea what was going on
