If you use C's malloc, you will also have to use C's free.
Yes, obviously. But the deallocator which contains the call to C's free
has to be invoked by someone, otherwise it's useless. So that is my
question: how should finalization and deallocation get triggered in this
scenario (where non-GC memory is used)?
delete will, as long as it is kept in D, call the deallocator method.
Unless the allocated memory is not registered with the garbage collector,
it will be ignored by the garbage collector, and you will have to manually
delete allocated objects. The point of using C's malloc and free is
exactly that - the GC will ignore your objects, and you are free to (that
is, have to) manage their lifetimes yourself.
