RAX: fffb880022cbafa8 That should be RAX: ffff880022cbafa8 You had a single bit in memory flip from a 1 to a 0. This is usually a sign of some kind of hardware problem. Also a bug in this code would be causing a lot of similar reports as it gets run on every process exit, and yours is the only one like this.
