Returning dynamic array from the function?

[SuperPrower]

I have a function that produces dynamic array of strings. I would 
like to return this array from this function. I understand that 
dynamic arrays are of reference type, and thus if I try to return 
array variable, I will actually return a pointer to the first 
element of the array on the heap. Problem is, when I return 
dynamic array and try to print it outside of the function, I see 
garbage in a first few elements.

My humble experience with languages like C++ doesn't really help 
with understanding how Garbage Collector (if it's because of it, 
because if I understand correctly, I can imagine memory being 
de-allocated because we get out of scope of local variable that 
points to the array, thus there are no more pointers to this 
memory, thus it gets de-allocated, but we still return reference 
to this memory, so GC shouldn't really free it?) can cause this - 
can anyone please explain me what's exactly going on and what 
would be the proper way to return dynamic array from the 
function? Thanks in advance.
