Description

With -version=GC root/array.d will leak memory.
But only when dim is 1.

This is because it is putting it into smallarray, instead of allocating memory.

It can be verified by setting SMALLARRAYCAP to 0 and removing the if statement in the destructor.

During my testing with dmd as a library it will result in ~0.5mb leakage. The test cases were small, but in much larger cases this could be quite serious for reusability.

This could be a by product of other issues, I do not know.
