I do not understand what you want to achieve, but maybe (ab)using 
the 
[`atexit`](https://en.cppreference.com/w/cpp/utility/program/atexit)from the D shared object to register a function *in* the D shared object at app exit?
Be-aware when [`dlclose`](https://linux.die.net/man/3/dlclose) 
*is* used on the D shared object, the app will crash due to the 
function-pointer pointing to already unmapped lib function is 
called by `atexit`.

I however never tried this, might not work.
