You need to dive deeper, that is beyond the secret commit 66f0a432564b ("Add resource managment."), to find what's happened before the epoch. ;) Anyway, there isn't anything special here, the thing has been here since the inception of memset.S with commit 2e0f55e79c49 (no shortlog available for that one). And it is clearly a bug, possibly just a leftover from a WIP implementation or whatever. And I can see Matt has already fixed that, thanks! Maciej
