I am not sure, but the GC may scan that chunk of voids. If you need a raw block it may be better to work with an array of uint. > Why can't the GC remove that data and how CAN I remove it? If you really need to remove it, then you may not allocate it from the GC heap in the first place, and use the C heap, with a malloc and then free. But that requires a full manual management, and for safety it's then usually much better to put in such memory chunk only data that doesn't contain references managed by GC. Bye, bearophile
