Interesting. Do you have a repro for this? Thanks! -- Andrei

Not yet, but while looking for one I found that this code 
triggers an assertion in Region.expand()
```
module test;

import std.experimental.allocator;
import std.stdio;

private alias AllocatorType = CAllocatorImpl!(AllocatorList!(
        n => Region!Mallocator(1024 * 4), NullAllocator));

struct Big {
        ubyte[1024] bytes;
}

void main(string[] args){
        auto a = new AllocatorType;
        foreach (i; 0 .. 100) {
                a.make!Big();
                writeln(i);
        }
}
```
