Unknown bug disallows growth of dynamic arrays

[solidstate1991]

Here's the offending function: 
https://github.com/ZILtoid1991/collections-d/blob/master/source/collections/sortedlist.d#L38

It causes to throw an exception with `Access violation reading 
location` and a memory address, int the function 
`_d_arraysetlengthT`. Variable `ti` is a TypeInfo_Array, `value` 
of this object is null.

Error happens when adding a sprite in this class: 
https://github.com/ZILtoid1991/pixelperfectengine/blob/master/pixelperfecteditor/src/app.d#L64
However, the same doesn't happen when the editor is being run.

Since leaving out any addition of sprites causes errors 
elsewhere, I was thinking that it might be a memory leakage 
issue. Could memory leakage cause such errors when attempting to 
grow or shrink arrays?
