Call the finalizer directly:
---
import std.stdio;
import std.experimental.allocator;
import std.experimental.allocator.mallocator;
class A
{
~this()
{
writeln("A.~this");
}
}
class B : A

~this()

writeln("B.~this");
}
}
void main()
{
B b = Mallocator.instance.make!B;
b.__dtor();
}

You're violating how inheritance is designed to work, though, so
this will leave the object in an alive state (the finalizer may
be called a second time on manual destroy call or GC
finalization, at which point the parent class' finalizer will
still be called).
