There’s a little bit more context (although not a lot) at the NASA blog which seems to be the source for this article. Basically it looks like they instructed it to go to different memory addresses and run whatever code was there in order to try to bypass any corrupted sections. One result was this memory dump. The reason they didn’t immediately identify it was that it wasn’t properly formatted in the normal way.

Fans of GURPS, or anyone looking to hear it in action should check out the podcast “the film reroll” (if you haven’t already). They play through films as RPGs using GURPS and it’s fantastic! They even had the creator of GURPS on once as one of many people playing Leonard in Momento. Also, there are absolutely no adverts.
