After reading the ticket you made, I was wondering if what you were 
looking for was:

http://www.digitalmars.com/d/1.0/class.html#allocators
http://www.digitalmars.com/d/1.0/class.html#deallocators

This allows you to use a custom allocator/deallocator and not worry 
about calling the correct ctor/dtor. If you want to change it for all 
classes, have a look at the _d_allocclass (or _d_newclass depending on 
your compiler/runtime) function in the runtime. If you change this you 
will need to recompile the runtime and it won't work for anyone else 
unless they use your modified runtime.
