Simply changing the targetType from library to dynamicLibrary breaks the code. What is going on with it ?

Looks like it's trying to build all files again, even though it shouldn't. I suggest you run "dub build --force --vverbose" to see the exact commands that Dub is executing.

For me it works both with "library" and "dynamicLibrary".

I did a fresh clone of dmd and added that as a dependency. That fixed it. Should've thought of it !! Thankyou.
