Something wrong with GC

The gc throws invalid memory errors if I use Arrays from 
std.container.
For example, this throws an InvalidMemoryOperationError:
>import std.stdio;
>import std.container;
>
>void main() {
>	new Test();
>}
>
>class Test {
>	
>	private Array!string test = Array!string();
>	
>	this() {
>		test.insert("test");
>		writeln(test[0]);
>	}
>}

and here's the stack trace
