Bienlein:
Is there a way to get around this?
Perhaps there are ways, but note that @nogc is meant mostly for stack-allocation. In general when in D you have to write lot of hairy code to do something, it means that in most cases you shouldn't do that something.
When calling delete t the protection violation
Don't use "delete", it's deprecated (despite it's not yet deprecated because D designers love to keep some important things in such Limbo for several years).
