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

Not sure what to do here
That looks like an error indeed.
But move the initialization of Array into the constructor.
