Friend, I think you nailed it. After adding this I haven't been
able to reproduce the segfault again:
```d
this(long n){
(){
cache = new typeof(cache);
assert(cache);
import core.memory;
core.memory.GC.addRoot(cast(void*)cache);
}();
// ...
```
It did always happen at random, so perhaps I haven't spent enough
time testing it yet, but I've gone far longer without it
segfaulting than ever before.
