Oh man!!!! That was it! I had forget about that! Funny enough, 
the reallocation tests I do letter when expanding the vector do 
include that but I had forgot to place it in the new (because I 
had the an old one and it included this) constructor I had made 
that only allocates memory!

Now, if only one could expect how and why "libc" knows that and 
doesn't just care to give me the memory I asked it for? Or it 
could be than D does something additional without telling us? 
Which can explain when this memory is only present when I assign 
the value to the "this._ptr` field!

Hope I don't have other memory related errors until I finish the 
compiler...

How can I thank you????
